I agree John,it is also what I would expect.Also if a person chose to get up on stage with amplification or not there was never any noise for either.If you went for a drink you would wait outside the room quietly until the performance was over or the end of a tune or song and then go in.I can remember a dozen or so people waiting outside the closed door for this moment.The person taking the money would supervise this and actually open the door at the correct time.There was never anyone crashing about with their guitar,jumping up in the middle of a song.If talking was done it was a quiet whisper.
I expect I am setting myself up for a bit of banter the next time I go to a folk club ,but even if this strikes home to a few noisy folkies out there then this is worthwhile.
