Many years ago, when the former WFLN Radio station was operating, they played Sousa's Stars and Stripes Forever, and called it a Monster Piano Ensemble. I have not been able to find that on Youtube, but in my search, I did come across the Irish Internationale Piano Competitions, where they have the eight finalists play on eight concert grand pianos, several classical orchestral arrangements. I picked THE WILLIAM TELL OVERTURE, because most people from my era associate the last movement with the popular radio and television series, The Lone Ranger. Last month you heard four outstanding organists play William Tell, here is eight equally outstanding pianists playing the full orchestrated version of Rossini's William Tell Overature.
