Elizabeth, in this speech which she described as "my 50th Christmas message to you," (her 1969 message was in writing and not broadcast) referred to the unusual number of trials and disasters that year, alluding to the foot-and-mouth disease outbreak and the 11 September attacks; viewers saw the occasion when the American national anthem was played at the changing of the guard. The Queen then spoke of the importance of faith when drawing strength in troubled times, and paid tribute to those who work for others in the community.
