Surely the whole point og songs with great chorus's if sung in a folk club is the joining in, asking them n ot to is a bit like giving someone a tasty sandwich but asking them to eat it without the middle b it!
Reminded me of a night at our club recenty, an old chap I thought had said join in the chorus, kept stopping with a disgusted look on his face when I did just that, turned out later he'd actually said 'don't' join in! His wife saw the funny side and said "he takes it all far too seriously"
