Jim, it may surprise you that I agree with much of what you believe folk song to be and its cultural roots and importance.
My difficulty is with you stating a belief as a fact, as you have in several posts over time,that folk clubs declined because they stopped presenting what you believe folk to be,therefore every one else stoppped going for the same reason.
A belief is not a fact,it is what you think is the answer.
Some may have stopped for the same reasons as you did, many stopped for completely different ones.
The work you did in the past catered for the people who were interested in the subject at the time.
There are still people interested today,just fewer of them.
Those who have a deep passion for a subject always find those who don't strange.
