Having said that, I found Carlisle's solo career somewhat disappointing. The Go-Go's brand of new wave and surf influenced pop rock was creative and interesting -- even at the end, they were still churning out solid material, such as "Turn to You" (featured on ERV in November 2012). In contrast, Carlisle seemed to take the safe route, recording well-crafted but less interesting pop songs. I wonder if part of the issue was losing the songwriting influence of Jane Wiedlin, who co-wrote many of The Go-Go's strongest songs (often with Charlotte Caffey who continued to work with Carlisle).
Anyhow, "Mad About You" was the lead single off Belinda Carlisle's 1986 solo album, and it did quite well, hitting #3 on the charts, while the Belinda LP peaked at #13. Carlisle would go on to have 5 additional top 40 singles and two additional top 40 albums before her success waned.
The video for "Mad About You" was directed by Leslie Libman, who would go on to become a successful TV director. The video features Morgan Mason, Belinda Carlisle's husband (in fact, they married in 1986) and Andy Taylor (of Duran Duran fame) playing the guitar solo, just as he did on the record.
Cool trivia fact: "Mad About You" was originally intended to be a Go-Go's song when the band briefly considered recording an album without Jane Wiedlin.
