In August 1977, Warsaw placed an advertisement in a music shop window seeking a replacement drummer. Stephen Morris, who had attended the same school as Curtis, was the sole respondent. Deborah Curtis, Ian's wife, stated that Morris "fitted perfectly" with the band, and that with his addition Warsaw became a "complete 'family'". To avoid confusion with the London punk band Warsaw Pakt, the band renamed themselves Joy Division in early 1978, borrowing the name from the sexual slavery wing of a Nazi concentration camp mentioned in the 1955 novel "House of Dolls". In December, the group recorded their debut EP, "An Ideal for Living", at Pennine Sound Studio and played their final gig as Warsaw on New Year's Eve at the Swinging Apple in Liverpool. Billed as Warsaw to ensure an audience, the band played their first gig as Joy Division on 25 January 1978 at Pip's Disco in Manchester.
