Jan. 22, 2014 -- It's over for Toni Tennille and Daryl Dragon.
The singing duo of Captain & Tennille are headed for divorce.
According to paperwork obtained by ABC News, Tennille, 73, filed for divorce from Dragon, 71, in Arizona on Jan. 16. The couple had been married for nearly 40 years.
In the 70s, Tennille and Dragon toured with the Beach Boys, for whom Dragon played the keyboard. (It was Beach Boys lead singer Mike Love who reportedly gave him the nickname "Captain.") Together, they released a number of hits, including "Love Will Keep Us Together," "Do That To Me One More Time" and "Muskrat Love." They also had a TV variety series on ABC.
In 2010, Tennille announced on her blog that Dragon had a neurological disorder similar to Parkinson's and was no longer able to play music as well as he had.
"[His condition] causes him to have tremors...pretty severe at times," she wrote. "Some days he does pretty well.... other days his playing is severely compromised."
