Video: Wilco and Feist - "You and I" on Letterman

Since we are really just a Wilco blog that posts some stuff about other bands sometimes I would be remiss if I didn't share this surprisingly very high quality video from last night's David Letterman television program featuring the rock band Wilco performing "You and I" complete with Feist. I wonder if when they recorded this song she knew that she would end up being the 7th member of Wilco?
