Charles was a lovely, happy guy and a "spark plug" sort of player. He seemed to be a natural. I am sure that is how he got connected to the Chicago Symphony program.
At this point, that's all I can add. I saw/heard him in dozens of gigs and some recording sessions.
Sorry I'm not eloquent right now. Maybe more later when I'm not thinking of dead musicians.
Why not start a thread asking for info/memories? Might get some stuff from some of us old folks.
