Mac Davis, the writer of Elvis Presley's "In the Ghetto" and a former ACM Entertainer of the Year winner, has died. He was 78 years old.

Davis died on Tuesday (Sept. 29), just one day after news broke that he was critically ill after undergoing heart surgery in Nashville. His manager of more than 40 years, Jim Morey, originally shared the news of Davis' decline and announced his death late Tuesday night:

Born Morris Mac Davis in Lubbock, Texas, on Jan. 21, 1942, Davis graduated high school early and moved to Atlanta, Ga., where his mother was living following his parents' divorce. After forming a rock band and working at a couple of record labels, Davis began his songwriting career as part of Nancy Sinatra's Boots Enterprises, Inc.; he also played in the studio and live with Sinatra during this time.

After writing songs including "In the Ghetto" and "A Little Less Conversation" for Presley in the late 1960s, Davis went on to enjoy a country crossover career of his own thanks to songs such as "Baby Don't Get Hooked on Me" and "Stop and Smell the Roses." Much of his success on country radio came after he won the ACM Entertainer of the Year award in 1975.
