79 (Antrabata), Complete Copenhagen Warm Ups (Wendy, original and reissue), Copenhagen 1979 (no label), Copenhagen Warm-Ups (TDOLZ, Empress Valley, LSD-both issues, Tarantura, and the issue with green/white artwork - no label), Dazzling Daze 1 (Moonchild), Great Return of Zoso (Empress Valley), & Melancholy Danish Pageboys Get It On (Cobra)
The tapes used for these titles are all from the same bootleg tape. However, they all differ slightly from each other.
TDOLZ, EV's two titles, Wendy, and the 2016 no label titles have the most complete introduction. Antrabata's is the least complete.
The green/white no label title has digital interference during the last half of Hot Dog, lasting through the first minute of Rain Song.
Cobra, TDOLZ, both EV, Wendy, and the 2016 no label titles are the only titles to feature a complete Kashmir. The rest are missing the last 2 seconds.
79, both LSD, and the no-label title share the distinction of being pissed on by "Rock Studios, ACS" after the performance.
LSD's two releases are very similar but not identical. The re-release has a cut during Rain Song but it's sound seems to be equalized a little better, being a little more balanced in places too.
Empress Valley's original and TDOLZ are similar in completeness and having louder sound levels. (EV's tape has been amplified the most.)
Wendy's title has some extra tape of the audience after two cuts. It could be possibly sourced from a second source. Other than that, it's very similar to TDOLZ and EV's second version.
The 2016 no label title is similar to the more modern titles, but doesn't have the extra tape mentioned on Wendy. It's strictly one source.
Moonchild's title is exactly the same as the no label title. Same cd times and everything else.
Wendy's jewel case reissue uses the same cds as the original.
With the exception of varying sound levels and Tarantura being a little bass heavy and unbalanced, these titles are similar in sound quality.

The tapes used for these titles are all from the same bootleg tape. However, they all differ slightly from each other. The two LSD's, Tarantura, and green/white no label titles are all missing the end of Kashmir.
TDOLZ, Antrabata, EV's second release, Wendy, and the 2016 no label titles are the only titles that don't have a strange reverb affect, lasting 20 seconds during the first half of the introduction. However, the Antrabata is missing the first half of the introduction anyway.
All of the titles are cut differently before No Quarter. Only Tarantura seems to have all of Robert's commentary. EV's Great Return is complete here but is achieved by mixing in a second source. All titles are cut after Rain Song, but for some unknown reason, TDOLZ repeats a 1 second section 5 times.
LSD's two releases are very similar but not identical. The original has a digital glitch during Over the Hills and Far Away. The re-release seems to be equalized a little better, being a little more balanced in places too.
Empress Valley's original title is most similar to TDOLZ in song completeness and sound. However, it is missing 20 seconds of tape after Achilles Last Stand and 14 seconds after Stairway To Heaven. Their tape has been amplified a touch more than the others.
TDOLZ, EV's second release, Wendy, and the 2016 no label titles are the only ones not having the strange reverb to return for the tape remaining after the performance.
Wendy seems to use a second source to fill in some gaps between songs, and/or, possibly falsely extend.
The 2016 no label title is similar to the more recent releases, but is strictly a single source title. It has an instance of static or digital glitch in the early part of the guitar solo after ALS.
Moonchild's title is exactly the same as the no label title. Same cd times and everything else.
Wendy's jewel case reissue uses the same cds as the original.
For the most part, TDOLZ, both EV, Wendy, and the 2016 no label titles are similar in content.
These titles are mostly similar in sound.

Blind Date (Empress Valley - original and reissue), Knebworth '79 (Empress Valley), Knebworth Day 1 (Moonchild), Lost Masters Knebworth '79 (Celebration 1cd - original issue and remaster), Past Present and Future (Empress Valley), Past Present and Future: Knebworth '79 SBD-AUD Matrix (Empress Valley), You'll Never Walk Alone (Tarantura2000, 3cd), & Welcome To the 1979 Knebworth Festival (Watchtower box & jewel editions)
On Celebration's original issue, there is an awful sound in the background similar to the Tara2000 release of the 11th. It is on the remaster too. The frequencies on the remaster are not quite as high. That difference is only minor. Both titles sound equally terrible.
Tarantura2000 has released this show, unbelievably without their weird trademark sounds in the background. A very bizarre choice for them since Celebration already paved the way for this date.
Tarantura's sound is better than Celebration and as mentioned (it is lacking the weird sound found on Celebration) BUT is still a very poor quality soundboard. This release is far more complete. The que stops are poorly placed, similar to old Tarantura titles.
Empress Valley's Blind Date and Watchtower are very similar. They both rely on the familiar audience tape to complete gaps after Rain Song and during Whole Lotta Love. The first half of the introduction is also from an audience tape, but may or may not be from familiar one. EV's intro is just a few seconds shorter than WT's. EV used a less complete soundboard tape for WLL. It uses 49 seconds of audience tape where WT uses soundboard tape. After WLL, WT has more time that EV and more of that time is soundboard. EV and WT have four to four and a half more minutes of WLL soundboard.
Overall, Watchtower has the most soundboard tape. It uses a little more than four minutes of audience tape to complete the whole show. It's sound is very similar to Empress Valley. They are both much better sounding than Tarantura2000, but they still lack a dynamic range of sonics. Watchtower has a couple of instances of very minor (faint) static spots.
Watchtower's jewel cased edition re-releases the cds found in the box set.
EV's Blind Date jewel cased edition re-releases the audio found on the original title.
EV's PP&F title reissues the audio found on the original title.
Moonchild's title is a direct copy of EV (same cd times and metadata), so it's missing way too much soundboard in Whole Lotta Love. Furthermore, there's a lot of errors during Achilles (5:27-6:58) not found on EV.
EV's Knebworth '79 title reissues Blind Date.
EV's PPF SBD-AUD Matrix simultaneous plays the soundboard and tape from the audience, but excludes Stairway. A replacement disc (EVSD_1751R) was issued shortly afterwards to include Stairway.
8-4-79 audience
79 (Antrabata), Knebworth (Flying Disc), Knebworth (Tarantura), & Knebworth First Day (Led Note)
Much time between songs has been removed on the FD title. Overall, 3.5 minutes are missing.
Led Note has more tape before and after the show than the other titles. It has 3 tape drags, 2 of which are during songs. Overall, it is missing 2.25 minutes of tape from between songs.
79's Hot Dog as a tape problem not found on the other titles.
Antrabata, Flying Disc, and Led Note's titles are similar in sound quality. The Tarantura is a good bit louder than the others and is likely one generation closer to the master.
8-11-79 soundboard/video soundtrack
Blind Date (Empress Valley - original and reissue), Dinosaurs In the Park (TDOLZ, 3cd), Final Cut (Celebration, 3cd), Knebworth '79 (Empress Valley), Knebworth Day 2 (Moonchild), Knebworth Festival (Tarantura2000, 2cd), Knebworth Festival 1979 (Jelly Roll), Past Present and Future (Empress Valley), Past Present and Future: Knebworth '79 SBD-AUD Matrix (Empress Valley), Past Present and Future: Led Bloody Zeppelin That's Who (Empress Valley), Robert's Last Stand (no label, 2cd), & Welcome To the 1979 Knebworth Festival (Watchtower box & jewel editions)
TDOLZ is sourced from a poor generation of the video.
Celebration uses all of the soundboard available and then uses the audience to complete White Summer and Robert's commentary closing the show. There are a small handful of "clicks" throughout the title. The clicks are not too noticeable and do not really compromise the title.
Robert's Last Stand is similar to CDM . It uses the same amount of soundboard and audience. There are also "clicks" on this title too. No Quarter has been moved out of sequence to place the show on 2 cds. Sound is almost identical to Celebration.
The Tarantura2000 title is strictly from the soundboard. The music does sound great and is much louder than Celebration's title. HOWEVER, just like their "Ayers Rock," they tweaked the sound way, way too much. Again, the audience now sounds like a bunch of birds. It is easily heard between songs and can be heard during brief quite spots in songs. Furthermore, the PA problems that plague this show and mark it's well known signature in the recordings, have been almost entirely removed. A few were equalized out while others were totally chopped from the tape, even during music.
Jelly Roll's release is almost identical to Tarantura2000. Like Tarantura, the PA problems have been removed after Black Dog and No Quarter entirely. The ones during and just after Over the Hills and Far Away have been modified, but a little differently than Tartantura's. Jelly Roll is even louder than Tarantura. The sound seems overblown in a few places, like as the first song ends and in other places.
Tarantura and Jelly Roll don't have the minor handful of clicks like Celebration but they do both have a small static problem during Whole Lotta Love.
Empress Valley's Blind Date and Watchtower are very similar. Neither use any audience sources since the soundboard/video tape used is complete. EV suppresses the first big PA problem during Over the Hills and Far Away. Both titles have a tiny drop during Trampled Under Foot. EV has removed some of RP's talking after ALS and may have cut a few seconds of taped shortly after Rock and Roll.
Watchtower's title seems to be a little louder and may have a touch more bass than Empress Valley, but probably wouldn't be due to a tape generation difference. Watchtower has a few instances of very minor (faint) static spots. Neither WT or EV have near the amount of bass found on Celebration's Final Cut and Robert's Last Stand.
Watchtower's jewel cased edition re-releases the cds found in the box set.
EV's Blind Date jewel cased edition re-releases the audio found on the original title.
EV's PPF re-releases the audio found on the original title.
Moonchild's title is copy of EV (same cd times and metadata).
EV's Knebworth '79 title reissues Blind Date.
EV's PPF SBD-AUD Matrix simultaneous plays the soundboard and tape from the audience. White Summer gets out of sync for serveral seconds, so you're hearing Jimmy play two guitars at the same time. The tapes fall out of sync again after Achilles and Rock and Roll too, so Robert is hear saying the same things twice.
EV's PPF Led Bloody Zeppelin title is a single forty minute disc of "multitrack remasters" of random tracks. Evening has a cut and four second repeat.
8-11-79 audience, sources 1, 2, & 3
79 (Antrabata, 2cd), In the Field (Reel Masters), Galactic Messiah (Empress Valley), Knebworth (Tarantura, 3cd), Knebworth - November 11, 1979 (TNT Studios)
The Reel Masters title is strictly from the second tape source. EV's Galactic Messiah is strictly from the third source to disc. The other titles are from the first.
Tarantura and TNT are missing most of the introduction and are missing a short sentence after Since I've Been Loving You.
All titles have a sound change a few minutes into White Summer. Tarantura's Black Mountain Side has a cut. This title is also missing tape after Achilles Last Stand, Stairway To Heaven, and after Communication Breakdown cuts out while Robert is still talking.
Antrabata has a cut between Black Mountain Side and Kashmir. After Kashmir, the guitar solo has a digital glitch and here is a cut with repeat after In the Evening. This title has the most tape after the show.
TNT's White Summer is split across both discs to keep from making a third disc. It is missing tape after Achilles Last Stand and Stairway To Heaven.
The Tarantura is a good bit louder than Antrabata and may likely be one generation closer to the master. TNT is also louder than Antrabata but so is it's background noise.
The differences between these titles are quite minor.
