Hüsker Dü great Bob Mould was the musical guest on Friday night’s episode of Late Show with David Letterman. He and his backing band of Jason Narducy and Jon Wurster ferociously tore through a medley of “Tomorrow Morning” and “Kid With a Crooked Face”. In fact, the performance was so loud, dust fell from the ceiling of the Ed Sullivan Theatre.
