Pete Townshend has been known to react without thinking first during concerts. He once punched-out a plain clothes policeman sent on stage to alert the band and audience at the Fillmore East to a fire in an adjacent building. At a recent concert by the Who in Hamilton, Canada (2/19), Pete reacted with derision to a sign a young fan was holding up imploring him to smash his guitar. Townsend said, 'Go away with that sign please, just go away with it'... adding 'Don't bring your children.' and then, looking at the seven year-old's father, added, 'I want to tell you two words but I can't because you've got a child here.' With that, Townshend clearly appeared to mouthed out the words 'F#&k off', leading to an early exit by the embarrassed father and daughter. The frequently prickly guitarist has since expressed his apologies to the girl and her father in a letter and plans to do so again in person.
