Bob Geldof and Midge Ure have revealed they are planning a major pop concert this summer - but insist that it should not be called "Live Aid 2".
Rumours about another concert have been circulating for months
The event will be part of a series of concerts around the world to coincide with the G8 summit in July.
"We'll have all the big names we can find," Ure told reporters at the Ivor Novello awards on Thursday.
The Streets' Dry Your Eyes was named best song musically and lyrically at the ceremony, held in central London.
But The Streets - aka British rapper Mike Skinner - lost out in the best contemporary song category to Franz Ferdinand's Take Me Out.
Geldof and Ure were at the ceremony to collect the best-selling UK single prize, awarded this year to Do They Know It's Christmas? by Band Aid 20.
"What started 20 years ago is coming to a political point in a few weeks," said Geldof.
"There's more than a chance that the boys and girls with guitars will finally get to turn the world on its axis.
"What we do in the next five weeks is seriously, properly, historically, politically important."
"It's big," said Ure. "And it's as petrifying as the build-up to Live Aid, if not more so."
The pair collected their award from Sting, who confirmed he would be taking part in the event.
"Bob called me up and said I was doing it," he said. "He doesn't ask you, he tells you."
Speculation regarding the event has been mounting over the last few weeks, with Madonna, U2, Sir Paul McCartney and a reunited Spice Girls among those mentioned in the possible line-up.
Brit award winners Keane were named songwriters of the year at the awards, while Duran Duran were honoured for their outstanding contribution to British music.

Snow Patrol, meanwhile, had to share their best album prize with recently departed bassist Mark McClelland.
Other winners included U2, whose song Vertigo was named International Hit of the Year, and Robert Smith of the Cure, who won for International Achievement.
There were further honours for Lou Reed, Sir John Tavener and Sir Mick Jagger and Keith Richards of the Rolling Stones.
Soundtracks were also recognised, with Enduring Love and the BBC's Blackpool winning best film score and best TV music respectively.
