And are the versions of Lapti Nek and Yub Nub in the earlier cd's the same as they sound in the movie? The only isolated versions (Deleted Magic menu audio) I've heard are different.

The Lapti Nek on the boxed set CD is the same that was on the original soundtrack LP from 1983- meaning that it is not the same as the movie version. I don't think the movie version was ever released officially.

I believe there are 2 different versions of the Ewok Celebration song included, though- the '83 LP version and the film version.
