Exactly so, curmudgeon!!

Dialog heard in a Seattle coffeehouse in 1959:--

(Guy requests song. I sing it.)
Guy: "But that's not the way the Kingston Trio does it."
Me: "Sir, first of all, there are three of them and only one of me. Second, I learned that song before the members of the Kingston Trio even met. And third, I learned it from the same record they learned it from!"

Similar dialogs happened fairly frequently, and I was not the only one.
