A demo record of a song written by John Lennon and Paul McCartney and sung by McCartney himself has sold at auction in Britain for STG18,000 ($A31,169).
The record It's For You was written especially for the late British singer Cilla Black and became a hit for her in 1964.
Black's nephew, Simon White, found the acetate record in his father's collection, mislabelled as being sung by his famous aunt, who died in 2015.
It was only later the voice on the recording was discovered to be McCartney's. He had sent the record to Black so that she could listen to the song.
"This is an important and previously considered lost piece of musical history," the Beatles Shop said.
