So do I. It was the night before my 21st birthday. My (then) girlfriend, future wife and I were strolling along a nearly deserted Richmond high street at about 10pm and saw an Evening Standard placard scrawled with "Kennedy Assassinated". I thought at first, because it looked so scrawled it was fake news (I guess we had it even then), but subsequent news stands had the same scrawled message so my actual birthday was a bit over shadowed by the next days headlines. I guess that makes it 57 years ago, strange how some events are frozen in our minds.
