I actually have the 1997 SE soundtracks. I need to go take a look at them, but each set is actually a 2 disk set with about 24 - 30 tracks for one film giving just about every snippet of music found in the movies. Which is fantastic because there is this great bonus track on ANH disk 2 titled "Binary Sunset, Alternate." If you have never heard this one before it is awesome!

The alternate score starts were Luke would have said "Yeah that's what you said when Biggs and Tank left" and goes on until the next scene (when looking for R2 the next morning). The music that was composed originally was much, much darker and more eerie. You see Luke looking at the sun sets and the music seems to be saying "The empire is out there and they will be coming. Nothing good is going to come from this and your future is uncertain." It's really cool. Gives a total 180 degree look at what that whole scene means. And it was all just a simple change in music.
