In April 1942 ITMA provided a command performance at Windsor Castle in the presence of George VI and his queen on the occasion of the 16th birthday of Princess Elizabeth. It was, notes Worsley, the first Royal Command Radio Show. The royal family were fans of the programme; a member of the Royal Household said that if the war were to end between 8.30 and 9.00 pm on a Thursday night none of the household would dare to tell the King until ITMA had finished.
