Pink Floyd bassist Roger Waters will be forever grateful to SIR Bob Geldof for persuading the warring rockers to reunite for the London leg of Live 8 in July (05) - because it felt like a "great weight" had been lifted.

Waters walked out of Pink Floyd in 1983 and now regrets it took 22 years to put aside his animosity with bandmates Dave Gilmour, Nick Mason and Rick Wright.

He says, "It was a great weight off my back to have a rapprochement with the three guys after all the enmity.

"Constantly, in my work, I am exhorting people to let go of entrenched positions, and that could be seen as hypocritical in view of the fact that, for all those years, I held an entrenched position in terms of the history and internal politics of Pink Floyd.

"If (Live 8) is the only time we play together for the rest of our lives, I will reap the benefits of those few days for the rest of my life."
