I should probably check, but I thought some of the duel has no music, whereas the whole duel has music in the Black-and-White-Music-Only version that DJ and ABC did?
Also, there's an alternate Sail Barge Assault on the SE soundtrack release. Obviously, as it's the ROTJ soundtrack it won't sound as good as the others, and ABC's restored versions don't have this track, but it's something at least.
