Huey Lewis tells the story in Kansas City Magazine (strong language edited):
Well, my dad was a jazzer and Zoot Sims died. And when Zoot Sims died, they had a benefit in San Francisco at Kimball’s or somewhere. …
So I take him and sit down … and then I get a tap on my shoulder. I turn around, and it’s Getz. It’s really amazing … he’s wearing his horn and taps me on the shoulder, and my dad turns around and Phil Elwood turns around. And my old man goes, “Holy s***!”
Getz says, “Why don’t you let me play on some of your s***? I can play that s*** too.” And I said, “Oh, why, yes sir, I’m sure you can.” And then he took a card and he wrote on it: “Stan Getz. Have sax, will travel.”
He played beautifully, and on the way home, my old man says, “If you don’t take him up on that offer, I will never, ever forgive you!”
