Who Is John Cowsill?
John Cowsill is the husband of Vicki Peterson, the lead guitarist and vocalist of the 1980s pop-rock band The Bangles. Cowsill is himself a musician: he was a member of the family group The Cowsills, who found significant success in the 1960s and 1970s, particularly with their 1969 version of the song "Hair." He also served as a singer and drummer in the Beach Boys' touring band for more than 20 years. In addition, he was the percussionist and backup vocalist on Tommy Tutone's 1982 hit "867-5309/Jenny."
Cowsill is the brother of Susan Cowsill, who was Peterson's bandmate in the Continental Drifters and the Psycho Sisters. The Peterson-Cowsill marriage thus connects two musical families that have worked together for decades.

Vicki Peterson married John Cowsill on October 25, 2003. According to Peterson's Wikipedia biography, the couple had been friends for many years before marrying: Cowsill's sister Susan had played with Peterson in both the Continental Drifters and the Psycho Sisters, so the two families moved in the same musical circles long before the wedding.
Since marrying, Peterson and Cowsill have collaborated professionally several times. In 2017, they joined actor Bill Mumy (Will Robinson from Lost in Space) in the band Action Skulls, releasing the album Angels Hear, which included posthumous contributions from bassist Rick Rosas.

They recorded the songs in their home studio with producer and engineer Paul Allen.
Before her marriage to Cowsill, Peterson was engaged to Bobby Donati, whose relationship with her ended when he died of leukemia in 1991.
