U2 gave CBS Sunday Morning a look behind-the-scenes at their Innocence + Experience Tour, taking them under the stage to show off their impressively vast collection of guitars, and above to look at the massive LED screen that takes over the middle of the arena crowd. They also sit down for an interview, where The Edge talks about his drop from the stage during the show’s opening night in Vancouver last week — “It was a moment of reverie where I just completely lost track of where I was on stage” — and Bono discusses his bicycle accident some more. The frontman also reveals that “Iris” almost didn’t make it onto the Songs Of Innocence tracklist. Watch the whole segment below.
