" True, The Weavers, Burl Ives, Woody Guthrie, Josh White and their contemporaries were occasionally heard on the radio, but they ... labored in relative obscurity most of the time."

C'mon now. Ives did a hit Broadway show, and had a regular Sunday radio show for several years. Josh White made ths national charts with "One Meat Ball" The Weavers had a bunch of hits, including "Irene" which, as I recall, had record breaking sales.

    The "folk" that got "hot" was largely pop in style and presentation, although, admittedly, a passel of more traditional performers got a shot at public notice along with the pop acts. On both sides of the pond.
