Dear Piers Cawley,

I have to say that I'm always suspicious of people who counter my arguments by suggesting that I am morally deficient in some way - I like to think that I'm as compassionate as the next person (I just don't believe in giving selfish idiots an easy ride!). I'm sorry to hear about your acquaintance's medical problem but doubt that he is typical. Anyway, I would hope that most people in the circle would have at least some inkling of such a persons problems and would make allowances.

I do believe, though, that the songs are important and should be treated with respect. I also think that other members of the session are important too - as well as any non-singing audience. If the majority of the participants have put a lot of effort into their performances it's not fair for them to be bored, and even embarrassed, by some git who can't be bothered to work at his/her craft - but still expects to be listened to.
