Here's Feist on Leno performing "1234." No flashy blue dress, but she does pick up a guitar. And boy does she ever class up the place. Note that that's Larry the Cable Guy on the couch. Anybody else think his new movie might possibly be the most utterly offensive thing ever put to celluloid? And have we here at Prefix ever posted anything from Leno's show before? Just forget all of that and vibe to how great the song is.
