Zach Braff, who directed and starred in Garden State with Natalie Portman, talks about the changes on the Star Wars Trilogy DVD:

I don't know much about Star Wars, but my buddy Donald Faison is an absolute fanatic. He showed me that not only did they add Hayden Christiansen's [sic] ghost to the end of "Return of The Jedi" in the new DVD's, but they changed the Ewok's song at the end of the movie!! What?! The Ewok's song was he best part of the entire franchise. My favorite part about it was that there was no Ewokese for the lyric, "celebrate the life". If you go back and listen to the OLD version, the song goes, "Yub, nub, eecheek ee wy-wy celebrate the life, yub -nub!" Classic lyrics. It's like re-writing "Let it Be" or that Celine Dion song from Titanic, it's just not done!

Thanks to Zach-Braff.com for the alert.
