The folk music scene is apparently dying, the audience has gone.

Ewan MacColl's 100 or so albums are regularly being re-issued.

Assuming that you think of what Ewan performed to be folk music, who is buying these regularly re-issued albums?

How did you re-act to Ewan performing British material accompanied by an American five strung banjo? Apart from Margaret Barry I can't think of any traditional singers on this side of the Atlantic using the instrument. Some might think of it as jumping on the bandwagon brought about by the interest in American music at the time.
You appear to criticise current singers who introduce new methods of accompaniment of folk material.

And please don't go into your usual "grave dancing" phase again.
