A Jimi Hendrix transfer
© AFP/FileLONDON (AFP) - Producer Dave Chapman stumbled across a squalling electric guitar version of "Land Of My Fathers" on the end of a tape from 1970, which he found at his recording studio in Crouch Hill, north London.
The recording was hidden at the end of a session by a long-forgotten band called the New Flames, whose bass player, Vivian Williams, was good friends with Hendrix.
It recalls the distorted sound of Hendrix's 1969 performance of the United States national anthem at the Woodstock festival.
And it is thought almost certain that Hendrix was in London on September 10, when the New Flames recorded their tape.
This was just over a week before he died at the age of 27.
Chapman found out before his death in 2005 that Williams had brought Hendrix to a pub next door to the Crouch Hill studio days before the guitarist died.
The party drank into the small hours thanks to an after-hours lock-in laid on by the landlord.
Could Hendrix have recorded the Welsh anthem that night? No-one knows, and fans debating the issue on the internet are split.
The tape is now owned by former record producer Martin Davies, who inherited it from Chapman on his death.
He is attempting to track down Vivian Williams, who originally came from the town of Crickhowell, south Wales, and is now thought to be aged 64, in a bid to clear up the mystery.
