Actually, thinking about it; the unused score is great material, but I can see why it was cut. For example: In the unused score, the last scene in the film opens on the Rebel fleet with a great "Force Theme" cue that has a almost magical quality. Problem is, there is nothing magical about this scene. The Rebels have been defeated and the final score reflects that, with a sad but somewhat hopeful rendition of the Force Theme. Sure, its recycled from earlier in the film (remember Dagobah?), but its more appropiate for this particular scene.

I'm pretty sure I just explained why Adywan is not replacing the film score in this post, heheh. ;)
