Err.. Folkdave - Kiveton Park folk club should be open tonight as it has been every tuesday for several decades... I would class that as very much a "traditional format" club.

But I agree with the rest of your post. The scene has moved on, it has become more commercial, people like to go to festivals with big name artists. Also venues have become different. There are very few pubs round me with function rooms as the pubs have been adapted so they can serve food. This means it is much harder to find a venue with a bar that you can run a folk club in.
