Sorry to say Nick things like this are becoming the norm rather than the exception.

I find the old mehod of "shusshing" about as offensive.Nowt wrong with a few of the audiance having a word discreetly with the offenders, after all it is their session

Bettsy's method is one I thoroughly approve of and have actually used on one or two occasions !!!

Not altogether foolproof though. I did stop singing in a session once, as the noise levals of two of the "audiance" had reached the point were the putty was falling out the window frames. I asked the two participants politely if it was ok for me to carry on singing, or were they discussing something of national import.

I was promptly rounded on and was told I was being very rude for interupting a private conversation!
