Very nice performance!
Since taking up the euphonium again after many years of inactivity, I have at times thought back to playing in high school and college. As a freshman in college (1972-73) I think we had 4 euphonium players in our Symphonic Band at the University of Wisconsin. I can remember one of them--I was thinking his name was Bob, but I couldn't remember his last name. Well, as I read your post about Dr. Robert Grechesky, a little light bulb flickered in the cobwebs of my brain. I would bet my like-new Besson 10 mouthpiece that he is the same guy I played euph with in college (I think he was a senior when I was a freshman). I guess the world of old euphonium players is sort of a small world.
