David Letterman had TV on the Radio perform Dear Science's "Dancing Choose" on a fire escape; Jay Leno goes one crazier and has the Brooklyn band playing on the same stage as Lance Bass. For better or worse, though, "Tonight Show" guest Bass doesn't step onto the stage until after TVOTR have finished powering through a confident, horn-backed rendition of the spazzy, spoken-sung song. It's still worth hearing, but sorry, Jay-- in the battle of the "Dancing Choose", Letterman has won this round. (via Culture Bully)[original version from Dear Science,; out now on Interscope/4AD]
