Raggy, I identify all of those you mentioned as writers of 'folk-styled songs' and I sing songs written by most of them. AFAIC, their songs fit into the repertoire of a folk-club very well, alongside songs which have come to us down the 'traditional' route.

The clubs which I attend and do my stuff in are all vibrant, happy places where a mix of those types of songs is the norm. Variety, as always, is the spice of life.
