Jenny Lewis and Jonathan Rice dropped in on Conan O'Brien Thursday night for a typically charming performance — but even if you were glued to the TV, you didn't see them play this track, "Scissor Runner," which RollingStone.com is proud to present now. (It was in our Top 50 Songs of 2010.) Thanks to Jenny, Jonathan and Conan for sharing!
