Larry was my first private teacher (around 1971 or 1972). I was/am a trumpet player, but my father didn't want to drive me the extra 10 minutes to Chuck Erwin's house, so I spent a year studying with Larry. He was a wonderful man, and helped get me started on trumpet. Like you, I think it was $5 per lesson. A year or two later we moved closer to Oxon Hill, so I moved over to Chuck Erwin. And a few years after that I started with Doc Reinhardt who got me to double on trombone, so I can make myself an honorary member here.
I later met his daughter Lynn (or maybe it was Lisa?) at Prince Georges County Youth Orchestra and carpooled with her to rehearsals. Unfortunately I haven't been in touch with her since high school.
It was only much later in life that I learned what an absolute legend Larry was. When you're just a kid you don't recognize what sets people like that apart. (At least I didn't

.)
