Blair, Bill and Bono take Davos spotlight

Davos, Switzerland - Davos regulars Bill Gates, Tony Blair and Bono sought on Friday to stir the collective conscience of the annual huddle of global leaders over the plight of the developing world.

Bono, the U2 frontman - a rare exception to the bar on celebrity delegates at this year's gathering of the World Economic Forum - was scheduled to join British Prime Minister Blair in pressing industrialised nations to honour their promises on aid to Africa.
