By 1983, fame and nearly constant drug use were having a bad effect on the duo. Marc Almond also formed the group Marc and the Mambas, featuring collaborations with The The's Matt Johnson and future Almond collaborator Annie Hogan, as an offshoot in order to experiment out of the glare of the Soft Cell spotlight.
By 1984, the duo had amicably decided to end Soft Cell and released one final album called This Last Night in Sodom (UK #12). Headed by the duo's final single "Down In The Subway" (UK #24), the album departed from its predecessors by featuring more live drums and guitars than previous albums. However, the controversial subject matter still remained true to the Soft Cell ethos, with songs such as "L'Esqualita" that glamourized transvestite culture in Manhattan.
