Throughout the series, Bush’s music isn’t simply used as colour. The Grannies theme works in short sharp bursts throughout the episode, similar to American sitcom soundtracks - like the quirky wonderfulness David Schwartz brought to Arrested Development (2003-19) - and the unusual (and funny) tempo and instrument combinations used by Ronny Hazelhurst BBC comedies like Some Mothers Do ‘Ave 'Em (1973-78) and The Two Ronnies (1971-87). The music is catchy, but also cheeky and a bit naughty, setting up the episode to sound more like a mainstream sitcom than a children’s show. With Bush’s character theme for the girls’ dress ups, the episode becomes something more than a story of play and distraction.

In an early episode, Grannies, Bluey and Bingo dress up as grannies “Rita” and “Janet” to keep themselves amused while their parents complete household chores. After “Mum!, Dad! Bingo! Bluey!” come new calls, like “violins!” and “trumpet!”. The new soundtrack album features three versions of the show’s opening theme tune, including an extended version and an instrument parade, adding a list of instruments for listeners to respond to. TV's top ten ear worms, from a television tragic The melody dances up and down the scale as the show’s characters dance on screen, punctuated with the delightful roll call of names and the show’s title. The theme instantly indicates something childlike with the melodica, an instrument second only to the recorder in the way it recalls primary school music rooms. Bush’s musical economy is brilliant, immediately setting the mood for the show.
