U2 are auctioning off a signed guitar for charity.
The 'With or Without You' hitmakers - featuring Bono, The Edge, Adam Clayton and Larry Mullen Jr. - have each scrawled their autographs on the instrument, which will be sold to raise money for the UK's leading music therapy charity Nordoff Robbins at the 40th anniversary of the O2 Silver Clef Awards in London on Friday (03.07.15).
As well as the Gibson Les Paul Music Rising guitar - which was played by The Edge during their recent 'iNNOCENCE + eXPERIENCE' tour - the priceless prize includes a signed vinyl copy of their 1987 album 'The Joshua Tree' and a framed gold disc of the LP, four VIP tickets to one of the band's upcoming shows at London's O2 Arena, and a personal tour of the stage at the show from The Edge.
Bids for the incredible lot start at £15,000 and can be made on Nordoff Robbins' website until 14:00 BST tomorrow (02.07.15), with these being carried into the live auction at the event on Friday (03.07.15).
Also at the prestigious event, acts including Iron Maiden, Kasabian, Duran Duran, Mark Ronson and Rita Ora will receive O2 Silver Clef Awards.
