Here is the official original cut/original audio as stated by film score monthly:
" In the final scene, there is no tracked music from "Yoda and the Force." The scene begins with the first establishing shot of the rebel fleet, then cuts inside the Falcon for Lando to say "Luke, we're ready for take-off" (but a differeny take of this is used). After Luke says (Voice Over), "Good Luck, Lando," scene cuts to inside the Rebel cruiser where Lando says, "When we find Jabba the Hutt and that bounty hunger, we'll contact you."
The comparison of the music however is this:
"Track 12, The Rebel Fleet/End Title: In 70mm versions of the film, the final scene began with this cue. Preparations of these prints began before the film was "locked," so the 35mm version contains several differences (see sidebar *the part just above this that I typed out*). The most prominent is the inclusion of extra dialogue and a few additional effects shots to the closing scene. The re-edited sequence required the tracking of a section of "Yoda and the Force" to precede "The Rebel Fleet." For both prints, a few bars of "The Rebel Fleet" were eliminated.
This track was called 'Finale' on the original album and the Gerhardt recording and "Finale/End Credits" on the anthology set."
Unfortunately, there was a lot of confusion with this score. Certain elements were missing and actually so was a lot of documentation.
in Star Wars, they didn't even know there was an alternate to Binary Sunset until they checked the recording schedule and saw one that was listed as "not used" when obviously something was used, they checked it and found the alternate.
Several alternates for Empire Strikes Back are left out of the set. The alternate end credits, the alternate Rebel Fleet, etc. My set includes all known alternates however.
With all that said, I could be wrong... It may be that the version on disc 3 is the "re-score" and that the one on disc 2 was the "original" BUT... because of the differences in sound quality and problems with mixing of "Rebel Fleet" on the SE, I still stand by my decision to put the tracks the way they are. The mixing of the track on disc 3 is wrong. The Celeste and the harp are mixed incorrectly and I am unable to fix that without the masters so lol...
BUT, if you want to switch them... it's not that difficult so do what you wish heh
If I had to give a guess... I'd say that the original is on Disc 2. That the rescore was to add some time to it and that's on disc 3 but notice they say that in both cases, some of the music is omitted. To me, that's odd. John Williams doesn't just leasurely compose music. The music is composed strictly to the film so if there was unused music in the "original cut," that means that the cut he composed to was probably one before the 70mm one and may have been the originator of the extra dialogue. That dialogue must have been removed and then that was what you see in the 70 mm cut.
John must have then been brought in to rescore the scene after that (which is simply skipping a few measures nothing serious at all and today would have been done simply through editing but in those days it was easier to record how you wanted it than it was to edit it. (also because the omited part has a harp glissando in it leading back into the used part.)
Then, they decided to reincorporate that dialogue but also add some effects shots to the beginning because George thought it wasn't long enough (this was documented in that Building an Empire edit I believe) or on the normal DVD's audio commentary (I actually think it was the audio commentary).
Anyways, they extended the scene, reincorporated the edited out material but I guess in a different way, which caused the music to not fit as it had been written so they edited the track, using bits of both versions. The effects shots were finished far late in the game (I think they said they were the last ones done and were rushed to get done and of course, Williams couldn't be brought in to re-re-score lol... so they tracked in music, edited the tracks they had to fit the new-new edit...
That's what I believe at least based on what I know and have read.
