Although it was a long time ago, and we queued for over an hour to get in, it was something I did not want to miss out on.  The Beefeater guide we had was informative, educational and entertaining - just like your article.  I had to go and hang over Traitors' Gate and cry with laughter, after the raven had a real go at the hapless American.  Actually, it was in September 1982.  I know this because I was on my honeymoon (first marriage).  My wife at the time suggested I would be beheaded if I did not behave myself.  Still got my head, but not the missus !! -
