When I was working in Bermuda a couple of years after leaving the RAF
I was having a lunchtime game of darts in the pub I worked in (living on the Job) when a visitor from a R N boat that was in the Dockyard asked me if I had ever sung in the Club at the Naval Base in Singapore
When I replied in the affirmative He sais " Thought I'd heard that voice before " and walked away.
Come to think of it - Is this a Brag ??
