Oscar Asche’s Chu Chin Chow was the most popular musical in Britain during World War I, playing 2,235 performances over almost five years. Much of its success was due to the era’s fascination with the Orient, and it contained accessible music by Frederic Norton that generally only hinted at exoticism.
Chu Chin Chow continued a tradition of Orientalist musical entertainments, perhaps most notably Gilbert and Sullivan’s The Mikado. The legacy continues in the 21st century, for example in Andrew Lloyd Webber’s production of Bombay dreams.
This according to “Chu Chin Chow and Orientalist musical theatre in Britain during the First World War by William A. Everett, an essay included in Music and Orientalism in the British Empire, 1780s to 1940s: Portrayal of the East (Aldershot: Ashgate, 2007, pp. 277–96).
