"but they can also socialise too, have fun, enjoy themselves,its not a religion,its a club not a sunday school or a church. or a place where po faced pricks pontificate,about the way Denis Murphy played a certain twiddle in 1954,.that sort of thing is best left to internet forums."
Clubs are were you (used to) go to listen to folk music - simple as that. that is (or should be) their main aim.
Of course there is no restrictions to prevent socialising down in the bar while you are there - as long as it doesn't interfere with the main purpose of the evening.
Nor should there be any restriction as to what form that socialising takes (within practical... etc constrictions). I don't really believe that you are proposing to censor the subject matter of a club audience's discussions and taking it upon yourself to decide what should or should not be talked about at the bar...... or are you?
I suggest you re-read what you have just written and bring it back to the class when you have got it right!
