Alan Longmuir was the Scottish bass guitarist for the 1970s pop group, the Bay City Rollers. His younger brother Derek Longmuir was a founding member and drummer for the group.
Longmuir was born at Simpson Memorial Maternity Pavilion Hospital, Edinburgh. In 1976, at the height of the band’s popularity, Alan Longmuir was replaced by rhythm guitarist Ian Mitchell, a man ten years his junior, who would in turn make way for Pat McGlynn. Tam Paton, then the group’s manager, alleged that Longmuir had tried to commit suicide.
