Literary references include J. M. Barrie's Peter Pan in "In Search of Peter Pan" (a song which also quotes "When You Wish Upon a Star" from the Disney film "Pinocchio"), as well as a nod towards "Arsenic and Old Lace" in the song "Coffee Homeground", which despite being similar in plot to the play, was inspired by a taxi driver who drove Bush once. Film references include "Hammer Horror", while although taking its name from the Hammer Film studios, is actually about a production of "The Hunchback of Notre Dame". The British television show "The Sweeney", a popular police drama from the 1970s, was mentioned in the lyrics of the song "Wow", which is a song about a gay actor. Touching on the same subject, "Kashka from Baghdad" is about a male couple who are forced to keep their relationship secret.
