Bono has admitted that he and the other members of U2 have all considered quitting the band - having been churning out tunes for more than forty years.
The 62-year-old musician - whose real name is Paul Hewson - forms the band alongside Adam Clayton, 62, David 'The Edge' Evans, 61 and Larry Mullen Jr, 61.
The band has been pumping out music since 1980 with hits including With Or Without You, Beautiful Day, and Sweetest Thing.
