In 1964, when they were teenagers at New Trier High School near Chicago, Michael Aisner and James Stein interviewed Louis Armstrong backstage at one of his concerts. In his boxers.
You can’t take it for granted. Even if we have two, three days off I still have to blow that horn a few hours to keep up the chops. I mean I’ve been playing 50 years, and that’s what I’ve been doing in order to keep in that groove there.
Aisner also interviewed Muhammed Ali a couple years later.
