This is such a great article, so we'll-written and researched.
Through happenstance I took part in a Juneteenth program in Providence RI today. A gospel choir I am part of was on the program. Only a few of us could do it, not the whole choir, but we brought it, singing "Oh Freedom" and "Woke Up This Morning With My Mind Stayed on Freedom." I was the only tenor, (as well as the only white person -- story of my life) and we had pretty hot mics, so everyone heard me individually, which is OK, I know my parts.
