Bruce Springsteen checks out the MGMT show at Bonnaroo

Bruce Springsteen stuck around Bonnaroo 2009 until almost 4AM to catch MGMT's headlining performance in the 'That Tent' on Saturday night. Bruce played around midnight earlier in the evening. The guy who caught it on camera posted "we saw dudes that looked like secret service scouting the place out...made jokes about the boss showing up, but then he really did. funny. this was during kids (obviously). taken right before the "secret service" cat made sure i was aware that filming the boss was not okay."

Reviews of the music festival say MGMT were all everyone was talking about all day Saturday. The tent was packed over an hour before they went on stage. When they did appear, the crowd burst into an explosion of glow sticks, beach balls and dancing. MGMT also played a new song titled 'Congratulations' off their upcoming album.
