In December 1980, original bassist Olavarria fell ill with hepatitis A and was replaced with Kathy Valentine, who had played guitar in bands such as Girlschool and the Textones. Valentine had not previously played bass guitar. Carlisle also related in her autobiography, "Lips Unsealed", that according to the band's view, another reason for Olavarria's dismissal from the Go-Go's was that she frequently missed rehearsals, due largely to her dissatisfaction with the band's move away from punk and toward pop. In late 1982, Olavarria sued the remaining members of the band for wrongful removal. The suit was settled in 1984. Olavarria later joined Martin Atkins' band Brian Brain.
