I frequented the Friday night folk club at the Noel Timpson Youth Centre in Cheetham Hill, run by Dave Davidson.
Went to a few that Mike Harding ran. The Old House at Home, an amazing little pub located right in the middle of ICI in Blakely, thanks to an ancient footpath. Ye Olde Golden Lion in Blakely Village. (maybe the Red Lion too for a while) and finally a pub whose name escapes me right opposite Heaton Park on Bury Old Rd.

Occasionally MSG when I could afford it.

Sometimes The Ring'O'Bells in Middleton.

Mostly (as we lived in Smithy Bridge within walking distance) the Fishermans at Hollingworth Lake which Jack and Mavis Lee ran on a Monday night, we still keep in touch with Jack and Mave.
They also ran another club which went mostly country music on either Kingsway or Queensway near Rochdale. (We left in England for Canada in 1977 so a lot of it is a bit misty)

Occasionaly the Poynton Folk Club, remember seeing Silly Wizard there if nothing else.

Bury Folk Club a couple of times, I think it was in a Cricket Club at that time.

My wife used to frequent the folk club at The Church Inn in Prestwich.

Somehow I think there was a couple more too, all of this was between 1966 and 1977.
