It was four unrelated one-act plays under that umbrella title, circa 1967. It had quite the cast, including George Grizzard, Martin Balsam, Melinda Dillon, and Eileen Heckart. It was a hit, running 756 performances. Replacements during the run included Larry Blyden, Irene Dailey, and William Redfield. It was directed by Alan Schneider, who'd directed Who's Afraid of Virginia Woolf with Grizzard and Dillon. Balsam won a Tony Award for best actor, Schneider was nominated but lost to Mike Nichols for Plaza Suite. A couple of years later, they did it in Los Angeles at the small Gallery Theater on Santa Monica Boulevard, which became the Pan-Andreas Theater, where we did my play The Good One. It was poorly reviewed by our curmudgeon critic, Dan Sullivan. I didn't see it because i was living in NY at the time. However, one of the producers of the then-casting The Mary Tyler Moore show did see it - they were having trouble seeing anyone they liked for Ted Baxter. Fortuitously, Ted Knight was starring in the play and the rest is history.
