Last night, Jersey rockers the Gaslight Anthem stopped by The Late Show With David Letterman, taking the stage for not just one track, but a whole concert, which you can now stream online. The group tore through an hour-long set comprised of old heart-on-sleeve classics like "Great Expectations," "American Slang," "The Wooderson," as well as some tracks from their new album, Handwritten, including first single "45." The crew also returned for an encore of the Who's classic "Baba O'Reilly."
