I agree with wolsey.
Behold, O God our Defender was commissioned for the Queen's Coronation at Westminster Abbey on 2 June 1953. I have a copy of the order of service, the first music in it (pages 2-12) is Parry's I was glad, the next music (pages 16-21) is the Howells, the final music (pages 182-3) is Gordon Jacob's arrangement of the National Anthem. On page 21 under the final bars of the Howells is printed Christmas Day, 1952. I was an 11 year old chorister at Durham Cathedral in 1953 and can't remember when I acquired the Coronation book.
