Jock was my Dad’s nickname in the Royal Marines. Until we went to 45 Commando in Arbroath. Which was full of Jocks :o)
Tony Osoba played the half white/half black illegitimate Scottish man called MacLaren in the wonderful TV show Porridge.
He was Sunny Jock.
But he met his match in the Cockney Fletch.
Tony talking (in real life) then him and Norman Stanley Fletcher in TVland.
P.S. I liked Lukewarm. He used to knit a lot :o)
