In 1988, Go-Go's lead guitarist Charlotte Caffey formed a band with the woman who would eventually be a one-hit wonder for the song "Bitch".
Not kidding. Meredith Brooks was a member of The Graces. I guess she was a 2-hit wonder.
There was a 3rd member- Gia Ciambotti. I add this because I don't feel like she should be forgotten.
On this song, the band's only hit, Caffey took the lead vocal.
Here is the band performing the song live. It's clearly here what roles everyone plays on the song.
