Simon joined U2 onstage at Madison Square Garden to sing a few of his music, “Mother and Child Reunion”.

The band performed Reed’s song Satellite of Love to the back drop of a video showing a recording of Reed performing the song.

Bono, who crashed his bike in Central Park and suffered multiple injuries last year, called out the woman who dialed 911 and the firefighters who responded to the call. They sat near the stage. She’s from Denver, however, she’s right here tonight.

During the encore, Bono once again thanked the former secretary of state for her work on promoting women and girls, but by that time, Clinton had already left.

Bono gave props to Springsteen for standing in for him on vocals for the World Aids Day RED benefit in Times Square when, he said, “I busted myself up here in the city”.

Bono had to get five hours of surgery to insert three metal plates and 18 screws to fix fractures to both his face and arm following the November bike accident, and underwent a second surgery to fix a fractured left little finger.

The rock star then handed over the mic to the woman, whose beauty clearly did not penetrate the skin.

However he was energetic and excited Thursday, working the complete stage in the loud area alongside guitarist the Edge, bassist Adam Clayton and drummer Larry Mullen Jr.

The Boss joined the Irish rockers at Madison Square Garden for encore renditions of “I Still Haven’t Found What I’m Looking For” and the Ben E. King classic “Stand By Me” during the band’s Friday, July 31 show, according to the Associated Press. U2 heads to Europe in the fall, beginning 34 shows there on September 4 at Torino, Italy.
