I totally agree with Joe and disagree with Psychomorris.
I have a severe hearing problem, having to wear two aids.
Unlike ones ears, hearing aids are not able to select or separate sounds but amplify every little noise.
One of the folk clubs that I attend is in a bar and I usually have a very enjoyable evening until the pub gets busy later in the evening,
then I give up.
I have enjoyed over fifty years of attending folk clubs here in the UK, both in Scotlnd and in England, and one of the reasons being the folk club etiquette of being quiet while someone is performing.
