Trooping the Colour
His Majesty King George VI is unable to attend Trooping the Colour due to ill health, so his place is taken by his daughter, Princess Elizabeth. The princess, riding side-saddle, wears a modified version of the regiment's uniform. The young Prince Charles rides alongside his grandmother, Queen Elizabeth (later known as the Queen Mother), and his aunt, Princess Margaret, in a horse-drawn carriage.
The colour trooped is that of the 3rd Battalion Grenadier Guards. The horse ridden by the princess at this event was called Winston, while the music played at the beginning of the troop inspection is 'The Triumphal March (Glory to Egypt, to Isis!)' from 'Aida' by Giuseppe Verdi.
