The most successful play ever mounted by the National Theatre in the UK, War Horse first opened in 2007 has since become a world-wide phenomenon, winning multiple awards playing to audiences in multiple countries.

Adrian subsequently re-arranged his original score for the show as a concert work War Horse Suite, and then as War Horse - The Story in Concert - a complete evening's performance in which Michael Morpurgo's classic book is read on-stage accompanied by the orchestra playing the music from the show.
