If anyone is interested in what English musicians are doing to draw from this 'tradition' right now, rather than concentrating on those admittedly excellent older albums listed in this thread, take a listen to a male/female duo called Megson. Their album' Smoke of Home' is self-written songs which are deeply saturated with an understanding of folk roots and an unashamd interest in contemporary working-class North-East England, while the subsequent album 'Take Yourself A Wife' has them singing & playing songs from that region which were written in the 19th century.

I sound like their press agent - sorry! - but they are outstanding & highly underrated.
