Washington, July 04: A rare 1962 recording made by Tom Jones in the lavatories at the YMCA in his home town of Pontypridd, South Wales, is set to go under the hammer at London auction house Christie’s.

The reel-to-reel tape, which is Jones` earliest-known recording to have survived, has been put up for sale in a rock and pop memorabilia sale.

The four unreleased tracks were recorded by the Welsh star two years before he became famous with the hit single ‘It’s Not Unusual.’

"These recordings have genuine historical significance as they mark the birth of the Tom Jones phenomenon," the Telegraph quoted a spokeswoman for Christie`s, as saying.

The songs were recorded by a TV sound man on an eight-track portable studio.

The sound man, who wants to remain anonymous, has now put the tape up for auction, where the recording is expected to fetch 2,000 pounds - 3,000 pounds.

Liz Williams, president of the Pontypridd YMCA, added: "Tom began his singing career here and apparently he often used to sing in the toilets.

"When it came to the recording, he wanted to use the toilets because he believed they had the best acoustics in the building," Williams added.
