Bono imitates Bill Clinton at New York conference

U2 singer Bono has poked fun former US president Bill Clinton by imitating his accent at a conference in New York.

The Irish rock star was one of a number of guests invited to speak at the Clinton Global Initiative event, and put on his best southern drawl to welcome Mr Clinton to the stage.

Speaking after the spot-on impression, Mr Clinton said: "I must be really easy to make fun of".
