Add.: Turns out "Don Brown's Body" was originally written for a Broadway revue called John Murray Anderson's Almanac, starring Cyril Ritchard and Hermione Gingold. "Don Brown," with Orson Bean as Mike Hammer, was the big hit of the evening, and Kerr incorporated it into her book "Please Don't Eat the Daisies" a few years later.
Read that, and then try to find a copy of Kerr's Please Don't Eat the Daisies, which includes "Don Brown's Body" as well as an almost equally good parody of Francoise Sagan's A Certain Smile, in addition to the funny domestic pieces that Kerr is mostly known for today.
I passed this kid sucking a lollipop. Don Brown dead, and him sucking a lollipop. I rammed it down his throat. I hate injustice.
