In the online meeting a week or so ago, David played a Red Norvo video and, when talking about it said, "I don't know why nobody has ever transcribed this solo.."
That was enough motivation for me. :)
To my ears, even though this was performed/recorded in 1960, it is an excellent example of the crossover point between ragtime and jazz. So much of what Red plays, from his low to the keyboard mallet technique to his linear construction, is reminiscent of the George Hamilton Green studies. Sometimes literally... check out measures 208-209.
