Roy is one of those Greatest Living Englishmen who never quite gets his due (Mojo award or no). The two cd comp from last year is a pretty good overview and scoops up all the highlights along with the best tunes from some of the less-than-great 80s / 90s albums. He is one of those fearsomely bright, open minded yet church hating humanists that we know and love and he displays none of the misanthropy / misogyny common to many of his somewhat embittered contemporaries.
I suspect he and Cope would have a lot more in common politically than musically but you never know. I get the impression that Roy finds rock and roll a bit silly these days and that any reference to its shamanistic aspect would be wholly lost on him outside of the strict bounds of 67-74 nostalgia.
If you are digging 70s Roy then there is a lot to be said for the early Michael Chapman records - not least the playing of a pre Spiders Mick Ronson - and also the Kevin Coyne albums on Virgin. Not quite Folk with an umlaut but coming from a place that's a long long way away from Maddy Prior and Planxty.
