AN unreleased track by Beatles guitarist George Harrison is to be auctioned along with a series of unseen images of the band.

The secret 1968 song, Hello Miss Mary Bee, comes on a reel-to-reel tape which also includes alternative recordings of several Beatles hits.

Unheard by fans, the Indian-influenced track was written for Harrison's good friend Mary Bee and produced around the time of his first solo album, Wonderwall Music.

It comes with letters from Harrison to Miss Bee while he was in India with wife Pattie Boyd.

The tape and messages are expected to fetch around £15,000 as part of Omega Auctions' Beatles Memorabilia sale at Penketh Business Park in Liverpool Road on Monday, September 11.

Also going under the hammer are 70 previously unseen negative images of The Beatles taken just before the death of manager Brian Epstein in 1967.

Auctioneer Paul Fairweather said: "Whichever lucky person buys the collection will have exclusive access to a piece of history from George's most influential period as both a Beatle and solo artist."
