In the animated legend 'Chicken Run,' composers John Powell and Harry Gregson-Williams used the kazoo to create a 'military' theme with a comedic twist. The kazoo is a simple 'mirliton' instrument that adds a buzzing, nasal quality to a player's voice. By using a large 'orchestra' of kazoos for the chickens' escape march, the composers parodied classic war movie legends like 'The Great Escape.' The choice was perfect for the film’s tone—heroic yet ridiculous. It showed that even the humblest 'toy' instrument can be used by legendary composers to create a memorable and effective cinematic identity, proving that humor in music is often about the choice of instrument.
