Susan Ann Sulley, formerly known as Susanne Sulley and Susan Ann Gayle, is a British singer and one of the two female vocalists of the synthpop group The Human League. Born and raised in Sheffield, England, as a schoolgirl in 1980 Sulley and her friend Joanne Catherall were "discovered" in the Crazy Daisy Nightclub in Sheffield by Philip Oakey, the lead singer and a founding member of The Human League. The pair were invited to join the new line-up, initially as dancers and incidental vocalists for a European tour. They soon were asked to provide full vocals by Oakey as an experiment. The girls' distinctive vocals rapidly became a signature of the new Human League, changing the band's style, its appeal to the mainstream public, and to its subsequent commercial success. Recruited into The Human League at age 17, she is a joint business partner in the band which is recording and performing to this day. The Human League has dominated Sulley's life; she has been a singer all her adult life and has never had any other full-time job.
