“It seems so hard for some of us to grow up mentally just enough to realize that there are other persons of flesh and bone, just like us, on this great, big earth.

I can do it gladly because I'm learning a little something. No matter how much they try to say that Brubeck doesn't swing — or whatever else they're stewing or whoever else they're brewing — it's factually unimportant.
Not because Dave made Time magazine — and a dollar — but mainly because Dave honestly thinks he's swinging. He feels a certain pulse and plays a certain pulse which gives him pleasure and a sense of exaltation because he's sincerely doing something the way he, Dave Brubeck, feels like doing it. And as you said in your story, Miles, "if a guy makes you pat your foot, and if you feel it down your back, etc.," then Dave is the swingingest by your own definition, Miles, because at Newport and elsewhere Dave had the whole house patting its feet and even clapping its hands....
