Longtime manager Tony Gottlieb said Seals, diagnosed with lymphoma two years ago, died Wednesday night at his daughter's home in Nashville.
With England Dan and John Ford Coley, Seals had hits including “I'd Really Like to See You Tonight" and “Nights Are Forever," both in 1976. His country hits in the '80s and '90s included “Bop," “You Still Move Me," “Love on Arrival," and a duet with Marie Osmond, “Meet Me in Montana."
“I've loved to play and sing from the moment I knew what it was," he told The Associated Press in 1992.
Seals, who is survived by his wife and four children, was in hospice care when he died. “He was very positive," said Gottlieb, Seals' manager for about 30 years. “He participated in several clinical trials to assist with research on this type of lymphoma."
Gottlieb said a major misconception about Seals is that he was a pop singer who came to country music. In reality, he said, Seals grew up singing country music and crossed into pop.
“He was raised in a very rural part of West Texas. His father was an amateur country singer, and he used to play with his dad. They were Hank Williams, Grand Ole Opry people. He was much more of a country singer than a pop singer."
Seals' older brother, Jimmy, was the Seals in Seals & Crofts, who recorded the hits “Summer Breeze" and “Diamond Girl" in the 1970s.
