Originally the title for Vaughan Williams's opera Sir John in Love, Fat Knight was conceived as a seven-movement orchestral suite that drew upon the opera and had, as its central character, Shakespeare's Falstaff. Vaughan Williams never completed the work and left only a two-piano score. It is from this score that the conductor Martin Yates has realised the Fat Knight suite, incorporating the orchestration from the completed opera.
