Springsteen chugs a fan's beer during concert in Philadelphia

Bruce Springsteen might be one of the biggest music stars ever, but he's not above mingling with the crowd -- nor is he a germophobe, apparently. During a concert in Philly, Springsteen jumped into the crowd for a passionate performance of "Raise Your Hand" and midway through the song made the (disgusting?) decision to chug a fan's beer. The crowd seems to love it, and those closest shout, "Drink up, Boss!" When he finishes, Bruce gets right back to singing without missing a beat and chucks the empty plastic cup into the crowd, leaving behind one dubious concert souvenir and a fan who has to make another trip to the concession stand.
