Was it agricultural labourers back from toiling in the fields or was it white collar townies who felt the need to get back to their roots?
Spot-on, Dave! Teachers, social workers, librarians, local government officers and the like must have been the organisers at practically every club I went to. Often they were that post-war first one of their family (self-included) to be selected for by that iniquitous 11-plus exam for grammar school and many to subsequent further education. Nearly all were inclined to the left politically though they did look a bit incongruous in their heavy corduroy trousers. collarless shirts and beards (especially the women).
