Canadian singer Michael Buble once challenged his drummer's friends to a fight when he mistakenly thought they had been heckling his performance. The Call Me Irresponsible star thought the group had been booing him. He tells U.S. magazine Blender, "One time I was singing at a club, and these guys kept booing me and at the end of the night I asked them to step outside. "But they weren't yelling, 'Boo! Boo!', they were yelling 'Lou! Lou!' because my drummer Lou Huger was a buddy of theirs. "I felt like a jackass."
