For the record, I agree with Suibhne that folk music (untutored, spontaneous, amateur etc) is only very rarely Folk Music (traditional-ish, oldish), and vice versa - and they're both different beasts from The Music That Is Called Folk (And Found In Designated Folk Contexts). I don't really care, though - while I enjoy being involved in folk music, I love Folk Music with a passion (and other music that does that indefinable thing it does - which is only sometimes to be found in Designated Folk Contexts).
