I never learned The Frozen Jogger myself, but I've definitely heard it, from John Dwyer and from others. It's not a myth.

Have patience, Winterbright. Just remember, in a world in which large numbers of folksingers are so (relatively) young that not only have they never heard The Frozen Logger (recorded by all sorts of people, including The Weavers), but they have never even heard of it, most of us who do remember the song are old geezers with Geritol stains all over our lap robes.

We're workin' on it. It just takes us a little longer to remember, that's all.
