Andrew Bird's performance of "Fitz & Dizzyspells" on Letterman a few weeks ago is very similar to his performance of the Noble Beast single on Leno on Tuesday--he shows off his impressive whistling, bangs on a guitar in a frenzied manner, and that weird speaker thing starts spinning near the end. However, this performance is a lot more "extreme" since rally car racer and motocross champion Travis Pastrana comes out on the end. Pastrana shows off his extremeness by awkwardly looking into the camera.

Noble Beast is out now via Fat Possum.
