I've always been bemused to see those who quote folk as a living tradition that evolves seem to put the brakes on at about the time they decided "hey, this is folk." Whether that be '50s, 60s or 70s. (Or '30s eh M?)

I go some weeks to a venue that books folk, blues and acoustic roots, by their advertising. When we had Martin Carthy last spring, I was delighted to see the large number of people in their twenties to whom he was a musical hero, ditto Martin Simpson last month. Yet I never see these people in local folk clubs. Their knowledge of the genre makes a joy to speak with them. When Johnny Dickinson asked for requests, those shouting out songs didn't have err.. high waistbands. 😇
Folk music is alive and kicking. Vic makes a good point.
