In 1956 Boosey & Co. published a "Military March No. 6" in the key of B major, arranged and orchestrated by Percy M. Young. According to the introduction Young indicates that certain manuscripts were made available to him from the estate of the Grafton family (of Elgar's niece May Grafton), including a short score dated March 1924 and separate violin and cello parts. Elgar indicated details of orchestration and expression. From these sources Young orchestrated 117 bars for full orchestra including harp (but not organ). However it appears to be substantially "The Empire March" composed for the British Empire Exhibition of 1924, including the Trio section "A Song of Union".
