The Prince of Wales has released some of the Queen's home movies, including several family holiday films, in his own personal television tribute to his mother, in which he also describes seeing her practising wearing her crown for the Coronation while giving them a bath as children.The Queen and the Duke of Edinburgh have long been known as keen amateur film-makers, and the Prince’s BBC One documentary, A Jubilee Tribute to The Queen, includes this brilliant clip (after the jump) of Charles and his sister Anne buried up to their necks in sand.
