Surfing the net earlier today, I discovered the Center for Jazz Studies at Columbia University and details of a talk held there on 28 February 2013 by Professor John Szwed on The Story of Jazz. Ellington aficionados will know that this is the collaboration between Duke and Orson Welles which unfortunately never got off the drawing board. It transmogrified, eventually, and after a fashion, into A Drum Is A Woman. I've emailed Professor Szwed in the hope that the text of his talk is available. In the meantime, I discovered the video, below, which, I'm sure, in part, covers this fascinating project.
The video and the programme notes copied below are from the Louis Armstrong Symposium held at The College of Staten island in 2009.
