I basically agree with Mike of Northumbria that the word 'entertainer' is not considered folk. People want labels on everything. I play guitar and sing mainly songs with a humorous edge. When people ask what I do I say folk music and this puts an image in their mind eg man with guitar like Bob Dylan (I wish). If I say entertainer the image is man with a mic. like Bruce Forsyth
Was Jake Thackray a folk singer?
