Jimmy Saville was pretty well known in the Royal Marines. He completed quite a few very hard physical tests and was always welcomed in the Corps wherever he went.
However, I was once at an occasion where because there were so many people to be fed we were all waiting in a queue at the Sergeants' Mess. He was an honorary member of the mess, but he also thought he could do as he liked and decided he wasn't going to wait in the queue. So he arrived at the head of it just as I was reaching it too and tried to get in front of me. I very politely told him that he might be allowed to get in front of other people but he was not going to get in front of me. He was then slowly edged backwards by others in the queue, until he was allowed in by a few wives who were also waiting. Maybe he was irresistible to women! He didn't seem a very likeable bloke to me though. But he brought a lot of publicity to the Corps.
