Here are some scans of one of my first parades with a drum corps. I am the guy holding the French Horn pointed at the ground. To my left is my first role model for drum corps: Kevin Middleton.
This is probably one of the last appearances of a marching tympani line with the Ambassadors; They were grounded in 1979, my rookie year. I don't know why the one player has no tympani. The keyboards were still marched in '79, carried by the skinniest girls in the corps which apparently was an unwritten rule.
