It’s 1971. Louis Armstrong has just finished a set at the Empire Room in New York’s Waldorf Hotel. He’s sitting backstage, ready to share his story with you. And the first words out of those legendary lips? “I shit myself tonight.”

But the revelations go a good deal further than bad kidneys and a potty mouth. In this engrossing 90-minute solo show written by Wall Street Journal critic Terry Teachout and directed by Charles Newell, they go to the man’s paradoxical core.
