New hunt for missing Beatles bass guitar

A guitar expert and two journalists have launched a global hunt for a missing bass guitar owned by Paul McCartney, bidding to solve what they brand "the greatest mystery in rock and roll."

The trio of lifelong Beatles fans are searching for McCartney's original Höfner bass - last seen in London in 1969 - in order to reunite the instrument with the former Fab Four frontman.

It disappeared without a trace nearly eight years later in January 1969 when the band were recording the "Get Back/Let It Be" sessions in central London.

The team now hunting for the guitar say it has not been seen since, but that "numerous theories and false sightings have occurred over the years."
