We were driving from a Mess Do in Swansea in the mid 70s and driving back to Cardiff late at night, we were all in mess kit. One that was not entirely drunk was driving. He had been told " You'd better drive, your'e too drunk to sing." We were stopped by the law in Cardiff. we unwound the window, the policeman put his head inside, he smelt the booze and said "Jesus Christ! get on your way, and be careful"
