U2's Bono has revealed to Q Magazine that his friends once trashed his car to bring him back down to earth.

Bono said: "The band just got too straight in the 80's. I mean, we were wrestling with some big questions but I kind of lost touch with my friends. I remember one night at home in Dublin, my father woke me up and said, 'There's someone trying to steal your car.'

"He had an iron bar in his hand. I looked out the window ... I had this tiny little Fiat Bambino. They'd wrapped the entire car in toilet roll and were smashing eggs on it. I didn't see it at the time but it was my mates saying, 'You need to lighten up.' "
