Night three of U2’s eight-night stand at Madison Square Garden was filled with surprises as Jimmy Fallon and The Roots joined the band Wednesday night (July 23).

Fallon -- who held a sign in front of his face that read “Singer with a broken finger” -- was invited by Bono to join the group in the circular stage at the far end of the catwalk.

“I’m a big fan of Irish people  that fall down and hurt themselves,” the Tonight Show host quipped before the Edge fired off the opening chords of “Desire.”

Fallon -- who donned the famed Bono glasses to mimic his moves -- even whipped out a harmonica to close out the jam.

"It's not easy being Bono," he surmised.

The song was followed up by another surprise appearance by The Roots for a rendition of the band’s love song to New York City, “Angel of Harlem.”

The show was attended by many celebrities and musicians including Sir Paul McCartney, Nile Rodgers, Alicia Keysproducer Steve Lillywhite and model Christy Turlington.

Highlights from the concert included a performance of “Out of Control” from the 1980 release, Boy, and the show closer, “One.”

As usual, the performance was broadcast on U2's Meerkat feed. Every night, a female fan is invited onstage to dance with Bono for "Mysterious Ways" before being handed a phone to broadcast the action globally over Twitter.
