Bruce Springsteen and Paul Simon sat in with U2 at Madison Square Garden as the band wrapped up their eight night run at the legendary New York City arena. Simon made his appearance on Thursday night for “Mother and Child Reunion” (the show also saw U2 cover Lou Reed’s “Satellite of Love” for Reed’s widow Laurie Anderson, who was in attendance).

Springsteen then joined U2 on stage for the final show of their run, which took place on Friday night. The Boss came out to help the Irish rockers with their own “I Still Haven’t Found What I’m Looking For” and a cover of Ben E. King’s “Stand By Me.”
