Nick always claimed he was an April Fools’ Day prank.
The story was that after his big sister Lesley was born his father said, “One’s enough”. So Nick’s Mum sabotaged the marital condoms. Before noon on April 1st she was able to say “April Fool!”
Sure enough, Nick was born on Boxing Day 1950.
I have no idea whether that was true or not, but remembering Romee, Nick’s tank driving, Nazi-escaping, Japanese-Prisoner-of-War-camp-surviving, multi-lingual German-Dutch-Jewish matriarch mother, I wouldn’t be at all surprised.
(There’s a memorable vignette of Romee in A Liars Autobiography, by Graham Chapman, the deceased Monty Python member. Chapman and other Pythons used to drink at The Monarch in Chalk Farm Road, the pub that Nick’s parents ran, and attended Nick’s wedding some time in the 70s).
