Reminds me of when I was helping with a school talent show. In the auditions (Liverpool school, so enough talent to need auditions rather than pressgang!), one lad was great on the concertina. Trouble was, the majority of his repertoire had titles like 'Kick the Pope' and so on. We eventually found something that had a neutral title and he got through. (He was the son of an Orange Lodge member and played in their band, by the way.)
