Here's what I was looking for:
Missing music from [the 1997 and 2004 soundtrack releases] of Return of the Jedi:
• Lapti Nek (film version)
• Lapti Nek (English version, "Fancy Man")
• Lapti Nek (album version)* (2:48)
• Leia's News (alternate)* (1:19)
• Ewok Celebration (film version)* (1:56)
• Ewok Celebration (album version)* (1:56)
• Jabba the Hutt (concert arrangement)**
• Max Rebo Band Instrumental Music (3:00)***
• Unused Source Music (not in film) (1:30)***
* are included on the 1993 box set
** About (1:20) of this piece was tracked into "Han Solo Returns" on the old album and box-set.
*** These selections were not included because they could not be found.
I assume Max Rebo Band Instrumental Music is the Sail Barge song. I guess the "could not be found" means the record label coulden't obtain the original master tape. I wounder how the site knows it was 3:00 long? And what's that Unused Source Music track about?
