Anyway, that's the position U2 found themselves in recently, when advertisers offered them that precise sum to use their song 'Where The Streets Have No Name' in a series of TV commercials.

Bono told Ananova.com that they were sorely tempted to give in and take the money. He said: "We almost did. We sat down. I know from my work in Africa what £12.5 million could buy. It was very hard to walk away from £12.5 million. So we thought, 'We'll give the money away.' But if we tell people we're giving the money away, it sounds pompous. So we'll just give it away, and take the hit. That's what we agreed."

He went on: "But if a show is a little off, and there's a hole, that's the one song we can guarantee that God will walk through the room as soon as we play it. So the idea that when we played it, people would go, 'That's the such-and-such commercial,' we couldn't live with it."

But if advertisers are still interested, we might be able to knock something similar up for, ooh, half that price. We've got a kazoo, and we're not afraid to use it!
