Jim. Your exact phrase is 'I told you what I believe'. That indicates it is your view or opinion. If that is not what you meant please tell me what you really did mean.

My alternative view of why folk clubs declined is that the massive increase of them in the 50s and 60s could not be sustained. The bubble burst. They fell out of favour, as did 60s music and bell bottomed trousers. These things are all cyclical. Nothing is new. They all come and go as does everything else and trying to hold on to what happened in the past is pointless.

And please note that I am not saying folk music is out of favour. It isn't. It is just the type of folk club that you are referring to has had its day.
