It's a real case of anything U2 can do, I can do better for Bill Clinton.
Sticking on a pair of shades, Clinton made a valiant attempt to replicate Bono's voice and said: "Well I'm Irish you know, and we Irish can imitate anybody."
In fairness to the former US President, he took Bono's impersonation of him in good spirits.
Christine Lagarde of the International Monetary Fund, Sheryl Sandberg of Facebook and Sudanese billionaire Mo Ibrahim were amongst guests at the Clinton Global Initiative in new York who rocked with laughter at the U2 frontman's impersonation as they awaited the late arrival of the former US president.

In a quavering southern voice, Bono spoke jokingly of Clinton's first encounter with him where he had actually thought Bono was the roadie.
"He wasn't really dressed right. I felt like the rock star on that occasion," said 'Clinton' aka Bono, leaning casually back in his seat in the familiar manner of the former world leader.
Attendees laughed but made uncertain eye contact with one another.
"But you know, we got to work on it and the foundation did incredible work, right now we've got affordable AIDs drugs for everybody all over the world so sometimes these talking shops do come good," continued Bono – with a pointed barb directed at critics of his 'good works.'
"No, no, it's David Letterman," joked Bono, as Clinton loomed in the background.
Amongst those in attendance was controversial former Taoiseach Bertie Ahern, spotted talking with Cherie Blair.
