I played the Maynard part of this at a St. Louis U basketball game in the late 70's. Since I couldn't rotary breathe on trumpet, I made sure I had a chair locked behind my knees. Sure enough, at the end of the long note, the room started spinning and I passed out. I had blown my chops, so I could only hit the last three notes. No one really cared about my blown chops since I was actually the drummer!
Similar thing happened to me in HS pep band at a basketball game. On that high B, the gym started spinning and by buddy playing trumpet next to me had to catch me.
