I don't know if this was already talked about or not, but will the unused John Williams score be restored?
Here is a video of the Mynock cave and the Jedi training scenes with the unused music re-incorporated into them.

And here is more unused music in the lightsaber duel. After he escapes the carbon chamber, when they're sabers clash, that's when I stop liking it. Then it gets cool again when Luke jumps over Darth Vader. So maybe just use parts of this score here.
