In the chapter "Turnabout Serenade", inside the Gavinners's dressing room are two references to the UK rock band "The Police". Examining the poster with the police officer on it will trigger a conversation about a band called The Police, and examining the red light on the ceiling will have Trucy talking about turning it on, with Apollo responding with "Don't turn on the red light", referencing the chorus to The Police's hit song, Roxanne.
