Interesting Fact: When the changing of guard occurs at Buckingham Palace they play traditional and sometimes more current songs. On September 13th 2001, two days after the terrorist attack on 9/11, Queen Elizabeth had them play the Star-Spangled Banner (the American national anthem). This was the first time tradition had been broken since its inception back in 1660.
She was the only Queen of England in my entire lifetime. I can only imagine how the people of Great Britain feel. Condolences from America.
