Bono was a surprise caller to RTÉ 2fm's 'The Colm and Jim-Jim Breakfast Show' this morning. Listen to show here.

During the show presenters Colm and Jim-Jim had joked that Bono was not able to hit the notes any more, following a discussion with Clannad singer Moya Brennan about whether the U2 frontman could perform 'In a Lifetime' with the band.

Bono then rang the duo live on air and said that he had lost none of his vocal abilities and that their show was the programme of choice in his car on the school run.

The singer was then asked whether he would sing at Jim-Jim's wedding, and he hinted that he might.

Bono also sang two of Colm and Jim-Jim's jingles live on air.

Afterwards, Jim-Jim said: "Sharon and I hadn't even thought of a wedding band for our big day but if Bono and the lads are free then I'm up for it!"
