Apart from these commissions, Walton's wartime works of any magnitude comprised incidental music for John Gielgud's 1942 production of "Macbeth"; two scores for the Sadler's Wells Ballet, "The Wise Virgins", based on the music of J. S. Bach transcribed by Walton, and "The Quest", with a plot loosely based on Spenser's "The Faerie Queene"; and, for the concert hall, a suite of orchestral miniatures, "Music for Children", and a comedy overture, "Scapino", composed for the fiftieth anniversary of the Chicago Symphony Orchestra.
