Mr. Flotsam and Mr. Jetsam

Mr. Flotsam and Mr. Jetsam were an Anglo-Australian musical comedy duo of the 1920s and 1930s. Mr. Flotsam's real name was Bentley Collingwood Hilliam (1890–1968) and Mr. Jetsam's real name was Malcolm McEachern (1883–1945). Hilliam wrote most of their songs, played the piano and sang in a light, high tenor voice. By contrast, McEachern had one of the deepest bass voices on record. Their material consisted of comic songs with rapid-fire delivery and songs with mild social commentary, as well as sentimental songs.
They are sometimes considered a precursor of Flanders and Swann.
Songs in their repertoire.
Their only film appearance is in the prelude of the 1936 Tod Slaughter melodrama The Crimes of Stephen Hawke.
The song "Is he an Aussie" features during the end credits for the 2013 film "The Purge".
McEachern, though, appears without Hilliam as Abdullah in the 1934 film "Chu Chin Chow" where his deep voice is heard to great effect.
