Ah, I love Youtube.
Vader and his crew of Imperial subordinates were caught on tape in a dance competition. A very entertaining one, actually. I was very impressed with Chewbacca’s performance. I didn’t know a Wookiee could dance like that.
This took place uncomfortably close to Hollywood producers. Still, if you can get over horrific visions of “Star Wars – the Musical” or “Star Wars on Ice” then you’ll love this video! Enjoy.
