Folk, I would argue, is beyond what would normally be described as ethnically divided, Folk has an ethnicity of its own?
Also, 'Fans' are on Mudcat. I am a fan, Nowhere near as good as those I enjoy, but I, like so many, like to sing, join in, do my spot, organise, etc. A Fan, A Folkie. A Singer, a perticipant. Of the Folk By The Folk for The Folk I say!
