Interestingly, the new music really doesn't start until you get back to Endor. Prior to that (i.e. during the planet celebrations) it is really just a rhythm intro that loops. It might be fun for somebody to try doing a seamless blend from the rhythm track into Yub Nub. There are actually two versions of Yub Nub on the Anthology Boxed Set. No idea off the top of my head if the alternate version would be more suitable to the greater length, but it too could be investigated. Shots of the Endor celebration could be truncated or removed individually as well. But since I prefered the new music I just left it as is. Another adventurous soul can build upon what I've done.
