Billy was also a fine composer and composed two cracking marches both recorded by the Jim Johnstone Scottish Dance Band with whom he played bass.
The Disused Railway is a catchy wee tune in 9/8 tempo while Craiglockhart was a good going 4/4.
(Craiglockhart I believe was originally called Hammy The Hamster's Farewell To Hutchison House and written to mark the family moving house/ The title was considered too long for putting on the record sleeve)
RIP Billy
