Rumors have swirled for weeks that a Live Aid sequel featuring megastars like Madonna, U2, Paul McCartney, a reunited Spice Girls and even Pink Floyd will be held in Hyde Park in early July, days before leaders of the world’s richest nations meet for a G8 summit in Scotland.

“There’s never going to be a Live Aid II,” Geldof said at the Ivor Novello songwriting awards ceremony in London, “but there’s something brewing.

“It’s big. And it’s as petrifying as the build up to Live Aid, if not more so,” he said. “We’ll have all the biggest names we can find. But it’s not just about big names, it’s about making a point.”

Geldof and Ure raised millions for Ethiopian famine victims with the legendary 1985 Live Aid show. Geldof has continued to campaign against poverty in Africa, and Prime Minister Tony Blair has made aid to the continent one of the key themes for Britain’s leadership of the G8 this year.

“Once more into the breach,” Geldof said. “What started 20 years ago is coming to a political point in a few weeks.

While details remain under wraps, one star confirmed he would be participating.

“Bob called me up and said I was doing it,” Sting said at the Novello awards. “He doesn’t ask you, he tells you.”
