You have to love that, just for the three levels of one-upmanship! I've got another for you, also not music-related. I was involved in negotiations for a client on a land purchase and in one meeting the agent for the seller, a very experienced fellow with 30 years experience, rather pompously started to explain to my client how wire transfers worked. You have to understand that my client was a very high-level executive with a very large data-processing company. In fact, he was the Chief Information Officer. He held up his hand to stop the other agent in mid-flow and said, "I already know about wire transfers. My company handles them for mutual funds and we do between 10 and 15 billion dollars worth of wire transfers every night." Not another word was heard from the other agent on the subject.
Sure, there are musical examples, just not quite as dramatic unless you happened to be there. There are stories of a trumpet teacher who, every time he had a new student, would rip off a three (or maybe four?) octave G major scale, put his trumpet down and say to the student, "ok, now you impress me."
But my favorite personal example is at my own expense! I was in competition for the affections of a rather attractive French horn player with another fellow who happened to be an outstanding French horn player. Over at his place once I noticed on his mantlepiece a Juno award. The Junos are the Canadian equivalent of the US Grammy awards. Yikes! I knew right then that he was going to be very tough competition.
But it is pretty hard to top that SR71 Blackbird story...
And that gives us a clue as to the musical envoi for this post. Oh, what is this "envoi" I keep referring to? Here's the Wikipedia article. It was something used by the medieval troubadours as a final verse to comment on what came before. So what better choice for this post than Marin Alsop conducting the BBC Symphony in John Adams' "Short Ride in a Fast Machine":
