Jimmy Fallon last night kicked off his reign as host of The Tonight Show over in New York. You may have seen that just a few high profile guests stopped by to wish him well. It seemed like everybody in show business was there - oh to be a fly on the wall in that green room! However, as we all know, you can't mark any big talk show occasion without our lads U2 there to mark it, and The Tonight Show was no exception.
The fellas came on to wish the new host well on his first show, and of course performed a little song for everyone - well, an Oscar nominated song no less. The band didn't take to the stage though, they just casually sat on the couch beside Will Smith and performed from there. Although, by the end they had the whole crowd off their seats.
