THE prestigious Mercury Prize ended in controversy when the British-only music award was given to an American band.

Antony and the Johnsons, the New York band whose singer was born in the UK, were named winners of the Nationwide Mercury Prize last night.

Their album, I Am A Bird Now, beat a shortlist of 12 including hot favourites Kaiser Chiefs, Coldplay and The Magic Numbers in a ceremony at the Grosvenor House Hotel in London.

The announcement immediately sparked controversy over the band's eligibility for the Brits-only £20,000 prize because singer Antony Hegarty was born in the UK.

Hegarty spent his early years in Chichester, west Sussex, and settled in the US aged 12 after a spell living in Holland.

Speaking after his win, the singer and pianist refused to be drawn into the argument about his nationality.

"It's interesting you would call me an American. I just feel really pleased to be a part of this," he said.

He said he was "utterly shocked" to win, adding: "It's a really prestigious award and I feel honoured to have won it. I've no idea what it signifies, I'm just taking it one step at a time."

Asked what he would do with the £20,000 prize money, he shrugged: "Maybe I should buy some clothes. I know I look a bit rotten."

He said of the other acts on the shortlist: "It's kind of like a crazy contest between an orange and a spaceship and a potted plant and a spoon - which one do you like better?"

Some of the other nominees appeared less than pleased with the results.

Walked out

British-Sri Lankan rapper M.I.A. walked out of the ceremony within minutes of the announcement.

The Kaiser Chiefs did not pass comment.

But when the nominations were announced a month ago, their drummer Nick Hodgeson complained: "He's an American, really. It's a good album, but it's daft he's got in on a technicality."

Hegarty was a chorister as a schoolboy in Chichester and his musical heroes are British - Boy George was his childhood idol and repaid the honour by singing on I Am A Bird Now.

Standing 6ft 4in and with a shock of black hair, the 34-year-old singer has a voice as extraordinary as his looks.

It has been likened to Nina Simone and gay magazine Attitude described his album as "the gayest thing ever recorded".

The band is based in New York and has been a fixture on the arts scene there for over a decade.

Hegarty often appears on stage with a Japanese hermaphrodite mathematician called Julia.

Winning the Mercury Prize will guarantee a huge boost in sales for Antony and the Johnsons, a hitherto little-known act.

When Ms Dynamite won in 2002, her sales shot up by 700 per cent.

Chairman of the judges Simon Frith said: "It is the most extraordinary album. It doesn't sound like anything else around. I don't think anybody could be unmoved by it, which is what a Mercury record should be all about.

"There must be a lot of people out there who have never heard it and I hope this win will encourage them to listen to it."

Of the controversy, Frith said: "We just listen to the records we are given. If he wasn't eligible then we wouldn't have been listening to it." Tweet
