Alan Longmuir, bassist and a founding member of the Bay City Rollers, has died.

The Edinburgh-born musician, who founded the band with his brother Derek, had previously fallen ill while on holiday with his wife in Mexico.

He was with his family when he died at Forth Valley Hospital in Larbert.

Longmuir formed the Bay City Rollers with his brother, Derek, and went on to massive chart success in the 1970s.

His family said that the musician would humbly describe himself as “just a plumber from Edinburgh who got lucky”.

The Rollers’ lead vocalist Les McKeown described Longmuir as “the original Bay City Roller”, while guitarist Stuart Wood said he would “remember the good times we had for over 40 years”.

The quintet, whose ‘classic’ lineup was completed by Eric Faulkner, had worldwide success in the early 1970s, with massive hits including ‘Remember’, ‘Bye Bye Baby’ and ‘Shang-a-Lang’.

Tartan-clad fans of “Rollermania” bought 120 million of their records, but in 1976 – as the band hit the top of the Billboard charts with ‘Saturday Night’ – Alan Longmuir left the group although he joined his bandmates in 1999 for a one-off Hogmanay show.

He also appeared in a musical Fringe show in 2014 – ‘And I Ran With The Gang’ based on his life, which, he said, had got him back into playing live, and leading to reunion shows in 2015 and 2016.
