Harold Snoad and Michael Knowles adapted the television script of Brain versus Brawn as a radio episode.
The surname of the character played by guest actor John Ringham was changed from "Captain Bailey" to "Captain Turner", presumably because actor Michael Knowles, who co-adapted the TV episodes for radio with Harold Snoad, made occasional cameo appearances as "Captain Bailey", including in the radio episode, A Stripe for Frazer.
