When somebody can tell me what folk music is, I might be able to accept that Seth Lakeman doesn't qualify, but it seems to me, by the time we have to bar everyone who fails to fit within the narrow boudaries certain posters want to lay down, we would be left with a very dreary scene.

It's the variety that makes folk music so vibrant. From shantymen to singer-songwriters, we should embrace (though not necessarily enjoy)it all!
