Singer and pianist Daryl Dragon, best known as “The Captain” of 1970s soft rock duo Captain and Tennille, has died at the age of 76, his publicist said on Wednesday.

Dragon died of kidney failure in Prescott, Arizona, on Wednesday, publicist Harlan Boll said in a statement.

Captain and Tennille were best known for their Grammy-winning 1974 hit song “Love Will Keep Us Together, as well as the hits “Muskrat Love” in 1976, and “Do That to Me One More Time” in 1980.

They also hosted their own television variety series from 1976 to 1977.

Toni Tennille, who married Dragon in 1975, was with him when he died.

“He was a brilliant musician with many friends who loved him greatly. I was at my most creative in my life, when I was with him,” Tennille said in a statement.

The couple divorced in 2014 but remained friends.
