This should really be turned on its head. Folk played in Country Music Clubs.   During the 70's-early 90's.. country had many followers, and a huge club scene. In some clubs, there were the idiots with 'guns' and southern flags, cowboy hats etc. which was a horrid stereotype. But they were social hubs for couples to meet. Country was also heavily featured on TV when it was at its peak.   CM Festivals were big until the promoters overstretched themselves and went bust. What has this to do with folk? Many country artists included Celtic and folk crossover songs in their acts. Some of the oldie names started in Skiffle groups. I think it went out of fashion when new country came along, when line dancing, and Karaoke nights divided the audience. Some clubs are still going - but the heyday of country clubs in the UK is long gone.
