Two-Trick Pony

I knew that well-known art-house actress Charlotte Gainsbourg (I'm Not There, Antichrist) was off into the music scene somewhat, but watching this clip of her performing "Trick Pony," on David Letterman about 5-6 weeks ago is a little bizarre, I have to admit.

It's a little odd watching a well-known screen performer on stage, and it's also odd that Letterman had to ask, "are you Charlotte?" upon taking the stage - really, Dave?
