Most times when we decide what to learn we make judgements about the content of the song and when we sing we make some kind of judgement about the audience.

Is their some kind of continuum between good judgement and some kind of censorship?

I guess PC can 'go mad' as people often say. But this can be an excuse for not considering some, usually a minority of the audience, are going to feel about the song.

Stereotypes are easy targets for humour. I guess people from Cheshire are sick and tired of being characterised as new-rich country fools with no sense of heritage, who live in a flat boring place and do made up Morris dances. I have heard people use such a stereotype and get a laugh but I guess the same people wouldn't use the same jokes in clubs in south Cheshire. Good judgement and some kind of censorship?
