Cowardy Custard is a musical revue and was one of the last Noël Coward shows staged during his life. It was devised by Gerard Frow, Alan Strachan and Wendy Toye. A book, also titled "Cowardy Custard", was published in connection with the revue, similarly celebrating the Coward image.
The Coward image is celebrated in the book "Cowardy Custard", but wasn't celebrated in the Noel Coward show "Cowardy Custard."
