I remember the good Captain.
He played at the Memorial Union at U of Iowa back in ‘69...
I remember The Captain too. I saw him one Sunday evening in the 60s at The Childe Herald, a bar in D.C. which has passed on long since. His brilliance was sometimes hard to see, but one song, Dachau Blues, was a diamond. It started out with a typical Delta Blues blues chant rhythm and blues chords, Dachau blues, Dachau blues, dem poor Jews, dem poor Jews ..... His point was, I think, that the Blues only works for personal and trivial sorrows. If you try to sing the Blues about some real calamity, like the Holocaust, its just ridiculous.
