Brexit is a bit more important, Jim. Folk music will not ruin lives, businesses or the economy. Your analogy is fallacious.

As to the tomes of documented folk music. Are you really saying that unless it is in one of the books you mention, it is not folk music? If so, how can we ever get new folk music? Are we destined to sing the same songs for all eternity. If so, I must start to agree with the MP that said his idea of hell was a folk club!
