An 11-second clip of the Beatles' only live appearance on the Top of the Pops, which was thought to have been be lost, has been unearthed in Mexico.
The silent snippet is all that exists of the Fab Four miming to Paperback Writer on the BBC pop show in 1966.
The original tapes were not kept, but it was recorded by a viewer filming their TV set with an 8mm camera.
The footage was shot by a family in Liverpool and eventually fell into the hands of a collector in Mexico.
The collector contacted Kaleidoscope, a Birmingham-based organisation specialising in locating previously missing TV footage.
"I think if you're a Beatles fans, it's the holy grail," Kaleidoscope's Chris Perry told BBC entertainment correspondent Colin Paterson.
