Remember when Prinny Margaret visited a secret Hampshire helicopter base in 1970 (?). All the above about eating and smoking applied, she was also (obviously) half asleep. Later discovered that she had been at Frank Sinatra's farewell concert (well, one of them) at the RFH the previous night and had partied on until late o'clock.
The clever (sic) PMC had discovered that Marlboro was her tab of choice, so got some in for the bar. Problem was the minimum order was around 20 000 cigs, most of which were still there a couple of years later when I was posted back......
