Bono does have a sense of humor. When Pet Shop Boys covered Where The Streets Have No Name, U2 took out an ad saying "What Have We Done To Deserve This"
or something like that.
looking for that old story I found this more recent one.
Pet Shop Boys slam Bono
Metro, May 27, 2007
The Pet Shops Boys have apparently taken a pop at Bono -- saying they are not sure whether U2 feel comfortable with him using his celebrity powers.
The flamboyant pop duo have just returned from a year-long world tour -- and have also voiced their doubts about benefit concerts.
Neil Tennant told the Daily Mirror: "People expect them (benefit concerts) nowadays. The Princess Diana concert is fair enough, but I feel more uneasy about the Al Gore thing.
"I've always been against the ideas of rock stars lecturing people as if they know something the rest of us don't -- it looks arrogant.
"It's not as if they have a private source of information. To state the obvious as if you are the only person that knows it is intellectually weak. Like Bono -- he uses his celebrity, but in doing so he increases his celebrity. I'm never totally convinced that the rest of U2 feel comfortable with that."
