Oh, there are so many; however, it just popped into my mind:
MEL TORME singing at a club in the Catskills.
Sinatra said Mel had the greatest voice in the world--[paraphrasing]
He was was known as "The Velvet Fog." Also, man, could that dude play drums! And, he had an ear that was just fabulous.
A good friend of mine was backing Mel at Don The Beachcombers in the Windy City. He was doing keys and running over Mel's charts at 4 in the AM before the first show next day.
My friend chose to use a more modern chord than was on the chart while Mel was reading the Wall Street Journel and "listening?"
After my friend finished the chart, Mel looked up and said, "Hey kid, you play nice but just play the chords that are on the chart."
Amazing stuff.

Bet nobody out there knows who was playing keys at Don The Beachcomber in those days of Mel and many others?
