(CNN) Daryl Dragon, one half of popular '70s duo The Captain & Tennille, died Wednesday, according to his publicist Harlan Boll. He was 76.

Dragon, whose ever-present captain's hat left no doubt about which half of the duo he was, died of renal failure in Prescott, Arizona, Boll said.

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

Tennille was at Dragon's side when he passed away, Boll said.

The duo's best-known songs included "Muskrat Love," "Do That to Me One More Time" and "Love Will Keep Us Together."
