and everything else we have lost

It has not been lost Jim. Just changed. The new formats may not suit you. The old formats did not suit others. In the 1960s and 70s there was no such thing as an open mic night. They now abound. 40 or 50 years ago there was nothing like the number of festivals we have now. Things change. If you want to run an old style folk club, fine, no one will stop you. But to decry what is happening now simply because it is not the same as it was then is a fruitless excercise.
