Sir William Walton’s coronation march Crown Imperial will mark the end of the Royal Wedding Service of Prince William and Kate Middleton, it was confirmed today.

The orchestral score, published by Oxford University Press (OUP), was originally commissioned for the coronation of Prince William’s great-grandfather George VI in 1937.

A specially abridged version of the piece will now be performed at the conclusion of tomorrow’s wedding between Prince William and Catherine Middleton — marking the bride’s entrance into the royal family.

David Blackwell, Head of the Music Department at Oxford University Press, said: “Crown Imperial distils the essence of British regal ceremonial in music. It is an arresting piece ideal for a royal event such as tomorrow’s wedding, and we are extremely proud that it is being performed on this important day.”
