I was involved running the university folk club in Lancaster in the late 60s/early 70s...but I dont recall if it was still active by the late 70s. i was busier on the pub session scene by then in Lancaster, and other musical projects. Names I remember from the Yorkshire House town club would be Bert Byram, and Gladys Muschamp who was the big cheese as I recall.
   The Plough in Galgate was the centre of a lot of folk and other musical activities in those days, though maybe wound down by 76: 70 would maybe have been the heyday for that pub.
