[3] Wark was also the composer of the score for Tulip Time, a comedy with music based on the play The Strange Adventures of Miss Brown by Robert Buchanan (1841-1901) and Charles Marlowe.
[5] In 1932 he was responsible for launching and managing Pasquale Troise and his Mandoliers, an orchestra of about 16 mandolin, accordion, guitar and tuned percussion players that made a series of BBC broadcasts between 1932 and 1933, and which went on to be the most frequently used band on the long-running BBC series Music While You Work (1940-1967).
[6] Wark's light music compositions include the novelty intermezzo Animal Antics,[7] Bouncing Ball (xylophone or piccolo solo), and Chrysanthemums for orchestra and piano.
Philip L Scowcroft has suggested that Wark used the pseudonym Michele Lesley for some compositions, such as Waltz Serene.
He was married to actress Violet Kearney (1907-1985) who appeared as a dancer in the 1934 film Say It with Flowers, scored by Wark.
