I was looking at the same thing until I read this guys post on Amazon:
Everyone already knows what's involved on the first disc of this package, so I'll just stick with disc 2.
DISC 2
"Pilgrimage" is the album version from Murmur.
"These Days" is the album version from Lifes Rich Pageant.
"Gardening At Night (Demo)" is a slowed down version played on electric guitar, which was re-recorded during the Reckoning sessions. The song has a certain beauty to it that is emphasized by hearing it at half speed.
"Radio Free Europe (Hib-Tone)" is the version that appeared on the original RFE single, back in 1981 on Hib-Tone records. This was also released on Eponymous. I like this version just as much as the one from Murmur.
"Sitting Still (Hib-Tone)" is the b-side to the aforementioned single and while it's the same recording that appears on Murmur, it's a different mix that I actually prefer because it has a lot more texture to it.
"Life And How To Live It (Live)" is taken from a classic 1987 show in Utrecht, Holland. A very frantic, high energy version with Michael also introducing the song by telling the story behind it.
"Ages of You (Live)" , "We Walk (Live)" and "1,000,000 (Live)" are all taken from a 1983 show in Boston. "Ages of You" is a great b-side that wasn't played that often, "We Walk" becomes a lot of fun when played live and "1,000,000" was only played during the early tours.
"Finest Worksong (Other Mix)" also appeared on Eponymous (though it was called Mutual Drum Horn Mix). This features additional horns by The Uptown Horns & Steve Berlin. Not radically different from the original, but nice.
"Hyena (Demo)" was recorded during the Fables of The Reconstruction sessions. It improved pretty dramatically when it was recorded for LRP, so this version is interesting because you can hear how it evolved.
"Theme From Two Steps Onward (Demo)" was recorded during the Lifes Rich Pageant sessions. This track has been widely bootlegged for years and now we finally have a clear and polished version. Would have fit nicely on LRP.
"Superman" is the album version from Lifes Rich Pageant. This was released as a single so it actually would have made more sense on the first disc.
"All The Right Friends (Outtake)" is one of the band's earliest songs. This version was recorded during the Murmur sessions and it probably has more character than the version that was re-recorded for the Vanilla Sky soundtrack.
"Mystery To Me (Demo)" is again, one of the band's earliest songs. This version was recorded during the Lifes Rich Pageant sessions. Probably the weakest song of the demo versions on this disc, but kind of fun to hear.
"Just A Touch (Live in-studio)" once again dates back to the earliest days and this version was recorded during the Reckoning sessions. It's a bit lifeless compared to the LRP version, but it's interesting to hear in this setting.
"Bad Day (Outtake)" was recorded during the Lifes Rich Pageant sessions and like "All The Right Friends", this version probably has more character than the version that was re-recorded for the In Time compilation.
"King of Birds" is the album version from Document.
"Swan Swan H (Acoustic Version)" comes from the Athens, GA-Inside/Out film and it's not radically different from the album version, as it's recorded with basically the same type of instrumentation, but there is a certain intimacy to it.
"Disturbance At The Heron House" is the album version from Document.
"Time After Time (AnnElise)" is the album version from Reckoning.
