The Zutons Dave McCabe sentenced
Dave McCabe, who broke a man's nose after his girlfriend was insulted, has been ordered to do 150 hours' unpaid work and compensate his victim.
The Zutons' frontman, 29, headbutted Peter Appleby during an alcohol-fuelled row outside a nightclub in Liverpool.
McCabe, who wrote the hit song Valerie which was covered by Amy Winehouse and Mark Ronson, reacted with violence after one of Mr Appleby's friends mocked his girlfriend's fur-collared coat, saying it looked like she had a beard.
The rock star claimed he had acted in self-defence but was convicted of assault by a jury following a trial at Liverpool Crown Court in September.
He was given a community order and told to pay the victim £1,500 plus court costs of £3,500.
McCabe, dressed in a blue shirt and grey suit and tie, agreed to pay the money within seven days.
McCabe's lawyer said the musician, who has no previous convictions, regretted the clash.
He said: "It was an over-reaction from this otherwise very decent man, in every respect he regrets it.
"It has been upsetting and he has found it has affected him very very deeply."
