A tatty book donated by Radiohead's Thom Yorke reveals the band may have been inspired by William Blake.

Oxfam volunteers leafed through the copy of Blake's 18th century poetry collection after it was recently donated to one of their bookshops.

Inside the paperback they were stunned to find lyrics from Radiohead's best-selling 1997 album OK Computer scrawled in the margin.

Lines from the song 'Airbag', that features on the album, were found by workers at the shop in Oxford, and appear to show that the album - regularly voted as one of the best of all time - appeared to have taken inspiration from Blake himself.

After rare book specialist Andrew Chapman, 48, looked over the book however, it was taken off the shelves for the measly 50p it was marketed for and now could fetch thousands at auction.

The Radiohead singer's lyrics are penned on the inside cover, with other notes scattered throughout the poems.

Andrew, a father-of-one, said: "I'm a big Radiohead fan, so when another volunteer, Alex Barker, showed me the book, I immediately realised that it shouldn't have been on sale for 50p and took it off the shelf.

"We realised that the book was of considerable interest as it showed the influence for the song and a direct link between Blake's verses and Thom's inspiration.

"Alex had been flicking through the poetry books on sale while he was stood at the till and told me to take a look.

"We knew it must have been one of Thom's books as we had been talking about another one that he had donated only the week before.

"The book is a tatty Penguin 1960s paperback of Songs of Innocence and Experience, but Yorke's lyrics and the annotations make it very special.

"It's amazing to think this song on OK Computer was inspired by the poetry of William Blake - this could well be the first draft of Airbag.

"I wrote to Thom Yorke, to let him know the book could be sold at auction and he contacted head office to say that would be fine for us to sell it as we saw fit.

"Thom came into the store about eight months ago with a few books to donate and this was one of them.

"One of the volunteers priced it at 50p and put it out but fortunately the mistake was spotted and it is due to be sold at auction in London - it could raise at least £1,200 for Oxfam.

"The Syria refugee crisis is one of our main priorities at the moment and this money could help provide tents, water and clothing for families who desperately need it.

"OK Computer is a great album. I remember seeing the band at Glastonbury Festival in 1997 when they headlined and the heavens opened.

"We have been told the estimate for the book is over £1,000 but there had already been interest in it. I wouldn't have thought it was a wild idea to hope for £10,000 at auction."

It's not the first time the books expert has stepped in to earn Oxfam a small fortune.

In 2008 he picked out a scruffy copy of Rumour at Nightfall, Graham Greene's third novel, which raised £15,000.

The Blake book is due to be auctioned in London on March 18, but no guide price has yet been confirmed.
