Yeah, as sung by Jabba the Hutt.
My choices would be "Blue Moon" by Max Rebo, "Hungry Heart" by the Rancor or "Itsy-bity teeny weeny brown and gold metal bikini" by Princess Leia.
It's a Star Wars chart extrodinaire!

Wouldn't that be Rebecca and not Leia?

Ooh, what about Luke singing "The Great Pretender" to Obi-Wan?

Ok, I'll go for the obvious
Boba Fett singing Weird Al Yankovic's "I Think I'm A Clone Now"
Or R2-D2 could do "Beep" by the #####cat Dolls

Or maybe Palpatine again singing the old Rolling Stones number, "Get Your Kicks Down Order 66"...
And nah, it's Leia for deffo. At least it is until payday...

Or Darth Vader, singing - "I cant get no -satisfaction" (think about that one - it'll come to you), threepio singing "uptown droid", R2 & R5 whistling the "the great escape" theme tune, Lando flying the Falcon down the Death Star trench humming the "Mission Impossible" theme tune; Obi-Wan, Anakin, Mace and Yoda singing "Bohemian Rapsody" (as spitting image puppets).

Yoda singing "It's Not easy Being Green", Chewie singing songs from Hairspray, Jabba the Hutt singing "Wide-Eyed and Legless" (think about it), and my favourite, Artoo and Threepio singing "Together in Electric Dreams"...
