I think there'd be a lot of interest in you creating an isolated score track, ABC. Your restorations of the soundtracks are unparalleled.

I'd say, if you're interested in creating isolated score tracks from your restored versions, start a new thread for it. I'm sure many (including myself) would be quite interested!

And the eventual goal would be a single, 2-hour-plus track (not several individual tracks), synchronized to the GOUT, that can be muxed to the video by whoever wishes to use it. Just be aware that there will (obviously) be several minutes of silence in the track, wherever there isn't any music playing in the film.

I'd sync to the 1980 theatrical stereo for purist's sake, but I don't see how there would be any issues whatsoever with using the 1985 or 1993 stereo remixes.

It might also be interesting to have two separate isolated scores - one with the music exactly as it is in the film, one with any and all unused tracks where they would have been in the movie (an "as originally intended by John Williams" isolated score, as it were).
