To Obama's delight, Bono admits he sidestepped a hug from George Bush

'Nice work with the hug dodge,' then-Senator told U2 superstar in '06

And once Bono got his big secret out of the way, a few more came out — including The Edge's confession that he once punched Bono.

"It was at one of those early gigs where it felt your life depended on it," The Edge recalled.

During the show, Larry Mullen's drum kit began to fall apart, forcing the drummer to take out some tools to fix it in the middle of the gig.

Unaware of the problem, Bono tried to carry on before realizing something was wrong. He lifted up the drum kit to find Mullen  trying to fix it. A nasty exchange ensued before "The Edge caught me with one," Bono confessed.

The pair also gave some details about their forthcoming "Spiderman" musical, which is expected to open on Broadway early next year.

The Edge revealed that most of the show's story will be told through song, and that the majority of the material will be new.

Bono playfully told the audience that the show will feature a "new" villain. The singer said the villain had appeared once in "Spiderman" comics, and was female.

U2 are set to play three concerts in Ireland's Croke Park next week as part of their 360 Degree tour.
