Wow, Fay, Hornets nest springs to mind. The Topic, the Grove, Morris Dancing, Country dancing, Tom Paxton had arrived, The Watersons, ( a big influence) Derek & Dorothy Elliot, The High Level Ranters. The Primary organ was (& still is) THE TYKES NEWS, all west Yorks folk history is there! This is a must for your research.- Put out an appeal here and someone will have ALL the back copies and more names will start appearing. One that comes to mind is musician John Browell & his wife Hazel, they've been around forever in the West Yorks scene(& I mean that nicely John), you MUST chat with them. I can give you his phone number if you've learnt how to PM.
Cheers Bradfordian (In Nottingham now though)
