RATM vs The X-Factor
Rage Against The Machine were guests on the morning show, hosted by Nicky Campbell and Shelagh Fogarty, and invited to play a live version of their song, Killing in the Name.
The band had been asked not to sing the final refrain, "Fuck you, I won't do what you tell me!" but singer Zack de la Rocha sang it anyway.
It was not until the fourth repetition that the breakfast show production team faded out the microphone and returned to the studio.
But Fogarty enjoyed revenge – of sorts – when she told listeners: "So buy Joe's records." [Source]
