Been reading an article on swearing & Scottish fiction (some sad individual counted 4,000 fucks in James Kelman's "How Late It Was, How Late") as research for my Billy Connolly book. I know Connolly very seldom swore when he played the folk clubs but if he did was there a policy on swearing onstage? Be interested to know if there were/are any folk acts who curse a lot or was/is that generally frowned on?
