Their biggest hit was “Love Will Keep Us Together,” but ’70s singing duo the Captain & Tennille are getting a divorce.
Toni Tennille, whose real name is Cathryn Antoinette Tennille, 73, filed for divorce on Jan. 16, the Prescott, Arizona City courthouse confirms to PEOPLE.
Daryl Dragon, 71, also known as the Captain, was a keyboard player for the Beach Boys before meeting his wife. They released their first album in 1974, winning a Grammy the following year.
Tennille revealed on her blog in 2010 that Dragon was suffering from a neurological condition similar to Parkinsons that causes him to have tremors, which she said were “pretty severe at times” and interfered with his ability to play the keyboard.
The couple have no children. RumorFix was the first to report the couple’s divorce.
