The revival of the 1940s-50s, certainly; a lot of people discovered it by that route. I'm just a little too young for that, but I do play with people who started out with Skiffle and Blues styles at that time. Bert Lloyd wrote, in 1959:

"... many young people, whose musical nourishment had been limited to whatever came to them in canned form from the Charing Cross Road, are looking to folk music for something that they can take and re-make as their own. The ceilidh, the folk-singing party, is becoming a part of urban social life, and the voice of the revival folk-singer makes itself heard in youth hostels, city pubs, skiffle cellars, even in jazz clubs. It is a curious but welcome phenomenon, this revival of folk music as a city music. It seems that many taking part in that revival have come to appreciate British balladry through their interest in jazz. A search for the roots of jazz leads to American folk song, and a search for the roots of American folk song leads the astonished enthusiast back home to his own traditional music."

Of course, it was all going on anyway, but it would be through Skiffle and the like that many people came to discover their own tradition. I picked up some old copies of English Dance and Song a while back; the edition for April/May 1953 has a photo of you on the cover, playing dulcimer at the Albert Hall. Just over a year before I was born! It's good to know that you're still doing it. Your influence on the revival in Britain is more considerable than generally realised, I think.
