well jim,
margaret barry once puked up over the front row at the marquis of clanricade folk club, and then carried on playing, i suppose you would say this is alright because it was a traditional singer doing it not a folk comedian.methinks your biased against folk comedians, me i am biased against anyone who is incapable., whether it be margaret barry or concertina players[ no name no pack drill] or folk comedians.
