In 1969 I was Joe'd off as Project Officer for the ROC Annual Camp at RAF Watton - several hundred Observers for each of 6 weeks. Commandant was Air Commodore Rixon (ISTR) who each Friday hosted a VIP lunch. First guest was the then Minister of State and as a naive youngster in ignorance I tried separating the Minister from his protection officer. Other mistake was when the VIP guest was to be the Duke of Norfolk. Woke in the middle of the night exclaiming "He's a (adjectival) Catholic" - which surprised the then Mrs W. I explained that I had just realised that the VIP lunch was Friday, the D of N was the UK's leading lay Catholic and we were planning to give him roast beef. Fortunately between Wednesday and Friday we manage to source a fishy alternative. The ROC were a committed bunch of boys and girls and good fun to have around.
