Blackcatter...I'm not sure about the usage of profanity on this site...but if some f***in' banjo player started to play behind one of my sean nos songs...out of tune...and irreverently (or irrelevantly..whatever be the case)...I would stop singin immediately (by that time it's useless anyway) and tell him to F off....not quietly but loudly and succinctly so everyone in the room is called to attention and realizes there is an a**hole alert.
Mille pardons to those who think this could be better said without pseudo profanity.
