When I had a radio station in college, I called it "Revolutionary Ensembles" for obvious reasons.
I had the pleasure of seeing him solo and with other groups a number of times, all excellent gigs. But perhaps the most interesting was running into him on the street in NY when I was younger. I said "Leroy Jenkins?" He was sort of surprised and was like "um, yes?" and I proceeded to follow him on his errands and talk about the music, and he graciously didn't shoe me away. It was really something for me at that time, and still is.
Rest in peace, Leroy. You will be missed.
