Breathtaking! Your research is incredible! Thank you.
Side note .. stunning to me also is the connection to Oscar Brown, Jr. .. one of my early introductions to jazz in my teens .. he was a fave. I’ve got his hit .. “Work Song” which I know verbatim and like for the music and rhythm. Duh .. I never really payed close attention to the words ..just sang them by rote. It’s about the chain gang and ‘servin’ my time.’ And there’s another song of his for sure about slavery, as I now recall. When you’re young and foolish .. that’s what you are.
