U2 asked to headline Glastonbury Festival 2011

U2 have been asked to headline the Friday (24 June) night of Glastonbury Festival 2011, organisers have revealed.

Organiser Michael Eavis has approached the Irish group, who had to pull the same slot at this year’s event due to frontman Bono injuring his back, but is yet to find out if they’re available.

He did tell the BBC, however, that two of the three headliners had already been booked adding that he was "absolutely thrilled" by the bookings.

Eavis also defended his singing during his cameo appearance on stage with this year’s Sunday night bill-topper Stevie Wonder where he joined in on 'Happy Birthday'.

"Obviously I was very flattered and I do sing a lot – I'm not afraid of singing – but the techie people didn't give me an ear plug,” said the organisers, "there was millions of people cheering at me which is lovely, and I couldn't hear the tune so I was having to wing it.

"And of course being a singer anyway – we do the chapel thing every Sunday, singing hymns and really enjoying ourselves – and so I can sing in tune but I didn't know what the tune was. So I was just lip reading it and making the best of it."

The Wonder-duet was the second time that Eavis had been asked to sing with a headliner this June, he also disclosed. He was also set to sing John Lennon’s ‘Imagine’ with Muse.

"But then they changed their minds,” said the 74-year-old dairy farmer, “so I got dropped by Muse and taken on by Stevie Wonder – wasn't that good?!"

Registration for Glasotnbury 2011 is open now.
