Morrissey kicked off his United States tour last night with a boisterous appearance on Late Night with David Letterman. Performing a new song called “Action Is My Middle Name,” he strutted and danced, mugged for the camera, and sounded in generally fine form. Which is great news for those seeing him at House of Blues in Atlantic City on January 12th, or the Sovereign Performing Arts Center in Reading on the 18th. For more information on those shows, visit the WXPN Concert Calendar here. Below, watch video from Letterman.
