It sounds like a "in house band" on the Jay Leno show playing an intro for Jay's guest, Darth
"and please welcome, Darth Vader" (rapturous applause).
Jay - "So, Darth. What are you doing these days?"
Darth - "Well, being a bad guy isn't the same any more". Jay makes a number of jokes about Gaddafi and Bin Laden.
Good stuff, guys!
