Coin toss? Draw Straws? Paper, Scissors, Rock? How do you decide who the 'opening act' is for a lineup that includes a lot of the biggest names in Rock? We have no idea. But we do know that Bruce Springsteen and the E Street Band will deliver the opening set of the Wednesday (12/12) mega benefit to raise money the Robin Hood Foundation will use to help people still struggling to recover from Hurricane Sandy. Closing honors go to Paul McCartney - and it's a safe bet that just about all of the big name's on the bill will share the stage when Sir Paul concludes his set. All You Need Is Love, Hey Jude, Come Together or Let It Be would seem likely numbers to end the night on - but the all-star lineup could also rip into something more raucous. One thing is for sure, not many people will arrive late. The E Street Band is scheduled to start promptly at 7:30. Bruce has also been confirmed as a special guest when the Stones play the Prudential Center in Newark, NJ Saturday (12/15). The Black Keys and Gary Clark Jr. also got guest invites to appear at the only Rolling Stones dates scheduled so far for the group's 50th anniversary.
