Mac Davis is perhaps best known for his role in North Dallas Forty in 1979, alongside Nick Nolte. He also had his own TV variety show in the 1970's. He was born in Lubbock, Texas on January 21, 1942, where he was raised. As a singer/songwriter, he wrote "In the Ghetto" and "A Little Less Conversation", both made popular by Elvis Presley. His "I Believe in Music" is likely his most attributed song.
