Feist w/ Indie Rock All Star Choir on Letterman

SYA probably wouldn't be an indie rock blog without posting this today:

That's Feist performing "1234" on Letterman. Her backing choir wearing all white and some flashy sparkly things include: The National, Mates of State, Broken Social Scene, Grizzly Bear, AC Newman (and new wife Christy!) and Nicole Atkins! Letterman has no idea that almost everyone in that choir has performed on his show before.
