 Although generally a slow and perfectionist composer, Walton was capable of working quickly when necessary. Some of his stage and screen music was written to tight deadlines. He regarded his ballet and incidental music as of less importance than his concert works and was generally dismissive of what he produced. Of his ballets for Sadler's Wells, The Wise Virgins (1940) is an arrangement of eight extracts from choral and instrumental music by Bach. The Quest (1943), written in great haste, is, according to Grove, oddly reminiscent of Vaughan Williams. Neither of these works established itself in the regular repertoire, unlike the ballet score Walton arranged from the music of Façade, the music for which was expanded for full orchestra, still retaining the jazz influences and the iconoclastic wit of the original. Music from The Quest and the whole of the Viola Concerto were used for another Sadler's Wells ballet, O.W., in 1972.
