By this point, it's a little absurd to label Bruce Springsteen's set at the annual Light of Day concert a "surprise." He's played the New Jersey charity event, which raises money to fight Parkinson's disease, 10 out of the past 14 years, and the only time he missed one since it moved from clubs to the 1,600-seat Paramount Theater in Asbury Park, he actually warned his fans a day in advance via Facebook.
