I like that tune as well. I think it might be a different section of the tune played right after the Boushh entrance as Chewie is taken to the dungeon. Either that, or there were three tunes.
These movie-version tracks were used in the 1985 documentary The Making of a Saga, so I wouldn't be surprised if they reside with that material, wherever it is stored. (It was a LFL production, but it's possible it was mixed elsewhere.)
Seriously how do you LOSE that gold? I've always wanted a full track from the Lapti Nek as it was heard in the film as well as the one while on the sail barge. I can't believe those never got saved/released. They've got to be somewhere. I would think it's kind of hard to lose something like that in the studios as big as Star Wars was/is still.
I'm not sure where I got it, but I have a recording I found of the isolated soundtrack from ROTJ during the sail barge scene. I'm guessing it was from a DVD/BluRay option, perhaps? The only drawback to it is the volume/clarity of the sail barge music goes up and down during shots taking place outside the barge versus inside it.
I don't know how people can be so choosy; this and the one in the re-releases are both terrible to me.:lol I've only ever been able to tolerate it when it was done up all metal by Anchorhead.
Unfortunately, this is the only source I could find it in its entirety. Really wish they'd release the full thing but, considering the climate now, I don't think that's a possibility. Especially since it's been like 10 years on since they made Shredisode IV.:lol
