Cairns (left) is angry at how he was treated on Pop Idol

Daniel Cairns, 22, of Oxford, was told by judge Simon Cowell he would never be a pop star on the show two weeks ago.

Now Mr Cairns is releasing a reply, called How High is my Waste (sic) Band? ridiculing the Pop Idol judge.

"It's time someone took a stand against his comments," said Mr Cairns, who plans to release the song before the end of the ITV1 series.

The song has been written with the help of Steve Ludwin, a producer and songwriter who has worked with Irish band Ash and has written a track for the forthcoming Guns N' Roses album Chinese Democracy.

Top of the Pops

The punk track features the lyrics: "How high is my waste band/ As big as my ego, as wide as my mouth/ How high is my waste band? If I don't like you I will say 'You are so bland'".

The song features backing musicians from the British punk band Little Hell.

Cowell told Mr Cairns he would never be a pop star

Mr Cairns, who was ridiculed after singing a version of Insatiable, by Savage Garden singer Darren Hayes, plans to release the single before any of the successful Pop Idol finalists release theirs, and hopes to get on Top of the Pops.

"If we can do that it will be quite a gesture, because Simon Cowell said I would never be a pop star," he told BBC News Online.

"If I can do that, then it gives hope to all the other people who have been insulted by him too," Mr Cairns said.

'No hope'

He said he did not think people would only buy it as a novelty single because he believed many were opposed to the music being championed by Cowell.

"I think people are going to buy it for what it stands for," he said.

"People who appear on the show are given no hope at all. Some of these singers might not have the best voices, but if they really try hard enough they'll get somewhere.

"Look at Robbie Williams - he has the right spirit and attitude."
