Bruce Springsteen, Bon Jovi, Billy Joel, Alicia Keyes, and Paul McCartney. These were just some of the musical guests as apart of the 12-12-12 Concert at Madison Square Garden on Wednesday night. The money raised went to the Robin Hood Foundation, which is assisting with Hurricane Sandy relief in New York and New Jersey. The concert was televised nationally and performances will be sold through iTunes to help raise money. The show was sold out and the minimum ticket price to get into the venue was $150 per ticket.
