Thanks for the link, Bardford. Also thanks to Metchosin for the transcription. By the way the boxer should be Louis, as in the Brown Bomber, champ at the time.
It's funny the way each person hears the names. I always imagined it to be "Beetlebaum", maybe because I had friends named ----baum. However, since the title only lists it as the William Tell Overture, I guess it's each person for themselves in interpretation. I did download it and re-listen and re-enjoy it all over again. Spike was a genius, of sorts anyway.
