The key Scots folk activists in the 1950s and into the 60s who equated with MacColl and Lloyd in England were Norman Buchan, Hamish Henderson, and Morris Blythman. Buchan was very active in the Partick CP, and Henderson was I think a CP member. Morris was too left wing for the CP, and was 'all out for a Scottish Socialist Republic' in the John Maclean model.
