Embedded Player Noah Adams and Melissa Block mark the passing of former Army Sergeant Keith Clark, who played "Taps" at President John F. Kennedy's burial ceremony at Arlington National Cemetery on Nov. 25, 1963. Clark played the wrong sixth note. People remember that musical mistake as emotion-filled, but it was due to rainy weather and temporary deafness after a 21-gun salute. Clark, 74, died last week in Florida.
