RAGE AGAINST THE MACHINE put the F Factor into their campaign to beat Joe McElderry to the Christmas No.1 spot by peppering an appearance on BBC radio with the forbidden swear word.
To be fair to the combative band, they were only singing lyrics - "*** you I won't do what you tell me" - from their song, Killing in the Name Off, but they had been asked not to by BBC Five Live.
"Sorry, we needed to get rid of that, because that suddenly turned into something we were not expecting," presenter Shelagh Fogarty told listeners after producers pulled the plug on RATM.
"Well, we were expecting it and asked them not to, but they did it anyway."
Just before the sweary incident, the band's Tom Morello had outlined the reasons behind their campaign to force X Factor winner McElderry and his The Climb single off the festive top spot.
"People in the UK are tired of being spoonfed schmaltzy ballad after the other and they want to take back their charts," said Morello.
"We're honoured that they've chosen our song to be the rebel anthem to topple the X Factor monoply."
