Mac Davis, the singer-songwriter behind some of country music’s most iconic hits, died yesterday in Nashville after undergoing heart surgery. He was 78. Davis wrote country hits for several major artists, including Elvis Presley’s “In The Ghetto” and “A Little Less Conversation.” In 1972, Davis had his own recording hit when his self-penned “Baby Don’t Get Hooked on Me” went to No. 1 on the Billboard Hot 100 and also earned him a Grammy nomination. A string of hits throughout the 70s led to him getting his own variety show from 1974-1976. In 1974, Davis was named the Academy of Country Music’s Entertainer of the Year.

Helen Reddy, who shot to stardom in the 1970s with her rousing feminist anthem “I Am Woman” and recorded a string of other hits, passed away yesterday at the age of 78. The Australian-born singer enjoyed a prolific career, appearing in “Airport 1975” as a singing nun and scoring several hits, including “Ain’t No Way To Treat a Lady,” “Delta Dawn,” “Angie Baby” and “You and Me Against the World.” Reddy retired from performing in the 1990s and returned to Australia.
