Rocker Bono feared he would be kicked out of U2 because of his obsession with curing poverty in the developing world.
The Irish singer has used his position as frontman of one of the biggest bands in the world to campaign on behalf of a number of causes - but admits it came close to destroying the Beautiful Day hitmakers.
Bono says, "They are hugely supportive of the work I do, but they are in a rock 'n' roll band and the first job of a rock 'n' roll band is not to be dull.
"When I do my rant on making poverty history, I have got LARRY MULLEN, our drummer, looking at his watch, timing me.
"There was one point when I thought, 'I'm going to be thrown out of the band for this stuff.
"People openly jeered and I felt like I was a weight around my band's neck for this kind of work."
