The most basic Star Wars question...

George Lucas is the world's richest ewok.

 

The Ewok song is actually called "Yub-Nub".

As much as I disliked a lot of the changes in the revised version of ROTJ, i thought the mellower, "new-agey" music was actually a big improvement... as cute and catchy as "Yub-Nub" was, the new instrumental music seemed to have a more serious, dramatic feel to it, and thus was better suited to the grand finale of an epic trilogy.

 

I agree, though I always thought it was "Yub Yub"!

From my review:

"Many others disagree, but I definitely prefer the DVD’s ending song to the old Ewok “Yub Yub” number from the original movie. Although I never developed a real dislike for the Ewoks, I did always hate that damned tune, and the newer one gives the film a more melancholy conclusion. It’s not a great number but it certainly betters “Yub Yub”."
