Billy Mack Jr., the son of Bill Mack, says Price died Monday afternoon. Price had pancreatic cancer.
Mack, a family friend, said he was acting as a family spokesman. The wife of family friend and spokesman Tom Perryman, a DJ with KKUS-FM in Tyler, also confirmed his death.
Price was perhaps best known for his version of the Kris Kristofferson-written song "For the Good Times" in 1970 that became a pop hit. He was one of the most influential figures in country music in the 1960s and '70s, helping define the genre's honky-tonk sound early in his career, then taking it in a more polished direction later.
