Belinda Carlisle late autumn of 1990, the Go-Go's reunited for a tour to support their first best-of album, "Greatest", including a new recording of the cover song "Cool Jerk" (The Go-Go's original cover was featured on their 1980 European EP, with a second version being released in 1982). A notable feature of the tour was an anti-fur campaign, where the band members supported the animal rights organization PETA.

Singer Donald Ray Mitchell joined the group as third lead vocalist. In 1988, they found their biggest hit with the album "What Up, Dog?", which featured the singles "Walk the Dinosaur" and "Spy in the House of Love".
