He had a unique talent and you can be sure there were events from his military service that were reworked and found their way into the scripts of Dad's Army etc. which of course would be a sign of his genius. Like a lot of people of my generation I've watched them all, several times, and this will be an excuse to get the collection down from the attic. What better way to acknowledge the genius that was David Croft.
A little bit of Dad's Army trivia. The shoulder flash worn by the members of the platoon featured the letters CP. This stood for Croft and Perry, the writers.
