By some quirk of early 1960's distribution, The Epiphone Texan guitar was distributed in the North-West of England (as opposed to the Casino which was distributed in the South-west).
The original owners of the guitar were Liverpool's The Fourmost, contemporaries of The Beatles and beneficiaries of hit Lennon and McCartney songs.
On a late 1960s cruise, The Fourmost sold it to the ship's captain, who sold it to Phil in the early 1990s.
Especially for the occasion, the lovely Don Gilchrist has cleaned it up ("what have you been doing with it?' he asked.)
