Bono still hasn't found what he is looking for. At what point will he just admit that what he is looking for doesn't and may never have existed? In fact is probably a figment of his imagination. And then he can just shut up about it all.
He's 60 now. He's forgotten what it was he was looking for. Maybe it was The Edge or his glasses. The sets are getting shorter as Adam Clayton's bladder isn't what it used to be.
