This one's a bit late, but it's still terribly awesome: Last Thursday Letterman had Bon Iver on to perform a rousing rendition of "Skinny Love" that has frontman Justin Vernon singing and rocking the guitar and the other three guys in the band working percussion in a drum-circle-esque set-up. "Skinny Love" is one of those songs that kind of worms its way into your subconscious-- It doesn't have much of a chorus, varied instrumentation, or many lyrics you can definitely identify, but you somehow find yourself humming it the rest of the day after you hear it.
