Iplay in folk clubs fairly regularly, my experience is that is rare for people to be made to shut up ,most people that go enjoy listening to the performer are respectful of the music and do not need to be told to shut up.
Vic, how many times have you told people to sssh in your folk club over the last 40 years, please answerr , if you do not I will assume you have never had to.
most of the ceilidhs i have been to, have been in the proximity of a bar., however i live in ireland, the polace where ceilidhs originate, ceili or ceildh is a gaelic word
