We have a thread up and running on the possible existence of the"folk police", and on this thread we have a reference to "folk music fascists" who object to singing "Farewell to Tarwathie" with a 5-string banjo. Accompanying songs with a banjo seems to me a perfectly commonplace thing to do, can we have a name and cicumstances for an occasion when anyone tried to prevent anyone from doing this? I have sung songs with some pretty weird accompaniments in my time, and I really can't remember a single occasion when anyone told me it was impermissible. Maybe I've led a sheltered life?
