I'm sure there is some pitch issues between the Albums but you can never compare the RSO finale with the film and expect it to match (except if you have the 70mm film version to look at) because it's another film version. The one that should match is oddly attached to "Ewok Celebration" on the 4th disc of the Anthology and that one is the 35mm film version of "finale" we all have on our precious "GOUT";)
Maybe I'm misunderstanding your last post, you probably know, but I just wanted you to know, so you don't work with that one in vain. The Finale/End Title can be a confusing one on that score.
