That's a good theory Naemanson m' boy.
However, I think that these days(as opposed to the 60's) the etiquette in folk clubs has been eroded somewhat.
Time was when you paid the same attention and good manners to any artist by keeping quiet between songs, unaccompanied, six piece jigs and reels whatever.
I can't help but think that we've lost something important here in the passage of time. If someone is putting him or herself on the line, the least you could do is give a fair and well-mannered hearing.
I'm not advocating this, but there was a time in 1967 at the Fitters Arms club in Walsall when the late great Alex Campbell- never the most patient of men- threatened to come among the audience and clip the ears of the people chattering away while he was singing.
Bring back the birch!!
