A rare vinyl copy of Darrell Banks' soul classic Open The Door To Your Heart has sold at auction in the U.K. for more than $23,000 (£14,000).

The London Records' pressing of the mint condition seven-inch record, which is believed to be the only one in circulation, was won by an anonymous bidder on the RareSoulMan.co.uk website, which crashed a number of times during the auction due to high volumes of traffic.

It went for $23,269 (£14,543). The record is thought to be the only one of its kind in existence because all the original versions were destroyed following Emi bosses' acquisition of the track's rights in 1966, and it was described by auction organiser John Manship as the "holy grail" for record collectors.

Open the Door to Your Heart was Banks' only big hit before his untimely death in 1970. He was shot dead by an off-duty policeman who had been having an affair with the singer's girlfriend.
