Bono Bono

U2 may not have been able to perform on The Tonight Show Monday, but that didn't prevent the audience from getting treated to one of the band's songs.

Donning an Army hat and red-tinted sunglasses, Jimmy Fallon offered an impressively accurate impression of Bono and led The Roots through a rendition of "Desire."

U2 was scheduled to perform on The Tonight Show every night this week, but were forced to postpone their residency after Bono was injured while riding his bicycle in Central Park over the weekend. The frontman underwent surgery after the spill, according to a post on the band's website.

"It looks like we will have to do our Tonight Show residency another time - we're one man down," guitarist The Edge, drummer Larry Mullen, Jr. and bassist Adam Clayton wrote. "Bono has injured his arm in a cycling spill in Central Park and requires some surgery to repair it. We're sure he'll make a full recovery soon, so we'll be back! Much thanks to Jimmy Fallon and everyone at the show for their understanding."

It's unclear when or if the band will make up the residency.

The band also offered high praise for Fallon and The Roots' performance. "How rock'n'roll is Jimmy Fallon ? How talented are The Roots? ... How sensational is this performance?" they posted Tuesday.
