A lot of these blues guys are insistent about what songs they’ve written that they didn’t get credit for. They don’t suffer fools gladly at all. Mance played “Key to the Highway” for us and he insisted that he had written that song back in the 1920s or 1930s. Today that song is considered public domain and is not credited to anybody. Big Bill Broonzy’s version is the first one I heard and then of course Eric Clapton made it famous as a rock song. When Duane Allman died, “Key to the Highway” was played at his funeral in Macon, Georgia. Mance swore he wrote it.
