Bruce Springsteen stunned music fans at a small Parkinson's Disease benefit concert in Asbury Park, New Jersey on Saturday night (15Jan11) by taking to the stage with headliner ALEJANDRO ESCOVEDO and host Vincent Pastore. The rocker hit the Paramount Theater stage for a set with pal Joe Grushecky at the Light of Day concert late on Saturday night and then wowed the crowd with a solo, acoustic version of his classic Thunder Road.
