Take That played for the first time in Belfast on November 18th, 1993, which would mark the date of this episode. They played once more in Belfast on October 1994, before Robbie Williams left the band in 1995.
The book Sister Michael is reading is "The Exorcist", a 1971 horror novel by American writer William Peter Blatty. The book details the demonic possession of eleven-year-old Regan MacNeil, the daughter of a famous actress, and the two priests who attempt to exorcise the demon.
The story of this episode was inspired by Lisa McGee's own experience. In 1994, she lied to get a day off from school to go to a Take That concert with a friend. A photo in which McGee was standing in a crowd ended up being featured on the front page of the Derry Journal.
