That is a Bobby Hoffman drill, by the way. I am particularly pleased with the marching and visual aspect of the show. We worked very hard on that all year.
Blue Meanies was intended as a "drum solo with backfield horn accompaniment". By the second tour the horn part had been dropped and it became a stand-alone drum solo which, as you say, fell flat. Our show underwent many changes that year. We were desperately trying to get our scores up with a somewhat stale show, management problems, and HUGE shoes to fill from 1972. Yes, the guard was amazing, as always. I was so thrilled to see this color video - hell, to see any video, from 1973!
