This album marks the return of Simon Gallup in the group; he had performed and composed with Robert Smith and Lol Tolhurst on the dark trilogy "Seventeen Seconds", "Faith" and "Pornography". Guitarist Porl Thompson, who had played guitar during the very early days of the band, and also played keyboards and saxophone during "The Top" tour, became an official member. Drummer Boris Williams, who had previously worked with Thompson Twins, finally joined the ensemble after playing with the band during the US leg of the 1984 tour.
