Editing The Go-Go's (section)

===Reunions and lawsuit (1990–1999)===
In 1990, the Go-Go's classic lineup (Caffey, Carlisle, Schock, Valentine, and Wiedlin) reunited to play a benefit concert for the California Environmental Protection Act, a 1990 ballot initiative. The band also entered the studio with producer [[David Z (music producer)|David Z]] to re-record a cover of "[[Cool Jerk]]" for a [[greatest hits]] compilation.{{citation needed|date=August 2020}}

In 1994, the same lineup got together again to release a two-disc retrospective entitled ''[[Return to the Valley of The Go-Go's]]'', featuring three new recordings. The single "[[The Whole World Lost Its Head]]" peaked at No. 21 on the Billboard Modern Rock charts and "bubbled under" on the US charts at No. 108, and became the band's first and only Top 40 hit in the UK, peaking at No. 29. The band toured again to promote the release; ex-[[The Bangles|Bangle]] [[Vicki Peterson]] stood in on several dates for Caffey, who was pregnant.<ref name=":0" />

In 1997, Schock sued the other group members, claiming that she had not been adequately paid for her contributions since 1986 and that a songwriting agreement with Caffey had been breached. The suit was resolved by 1999 and the Go-Go's toured regularly from 1999 onward.
