Noel Gallagher is among those taking part in the project

Razorlight, Paul Weller, Rod Stewart, Dirty Pretty Things and Ozzy Osbourne are also lending their support to the Gibson Guitartown campaign.

They will each come up with a design for a guitar to be displayed around London as public art this summer.

The guitars will then be auctioned off to raise money in September.

Money raised will be given to The Prince's Trust, Nordoff-Robbins Music Therapy and the Teenage Cancer Trust.

Hand paint

Blunt said: "I am really pleased to be associated with this amazing project which aims to raise lots of money for three fantastic and worthy charities."

Other confirmed names include New Order, The Kooks and James Morrison.

Each musician will be paired with an artist who will hand paint their designs.

Pop artist Sir Peter Blake will turn Paul Weller's design into reality, while Osbourne will team up with cartoonist Gerald Scarfe.
