Buzz Cason, Songwriter Best Known for ‘Everlasting Love,’ Dies at 84

Buzz Cason, a guiding force in the early days of Nashville rock ’n’ roll and a writer of the pop standard “Everlasting Love,” a surging profession of undying devotion that reached the pop Top 40 in four consecutive decades, died on June 16 at his home in Franklin, Tenn. He was 84.

His death was announced by the Country Music Hall of Fame and Museum. The announcement did not specify a cause.

A pivotal figure in Nashville’s evolution as a recording hub, Mr. Cason had a hand in virtually every facet of the music industry. He sang, wrote and published songs, as well as producing records and operating his own recording studio.

He had his biggest success as the writer, with Mac Gayden, of “Everlasting Love.” The R&B singers Robert Knight (1967) and Carl Carlton (1974) recorded hit versions of the song, as did Gloria Estefan (1995) and the ad hoc pop duo Rex Smith and Rachel Sweet (1981). U2 released a stripped-down take of “Everlasting Love” as one of two B-sides of the 1989 single “All I Want Is You.”

“We didn’t know what we had,” Mr. Cason said of the song in an interview at an event held in his honor at the Country Music Hall of Fame in 2014. “It was a really great radio song.”

“Everlasting Love,” in its many versions, has received more than 10 million plays to date, according to the music rights organization BMI. It is among the most successful songs in any genre to come from Nashville.
