Country music's legendary bad boy Waylon Jennings died Wednesday at his Arizona home after a long battle with diabetes. He was 64. Jennings — who recorded some 60 albums over the course of his four-decade-long career — was best known for his hits "Good-Hearted Woman" and "Mammas Don't Let Your Babies Grow Up to Be Cowboys," both duets with his fave partner Willie Nelson. He also narrated the '80s TV classic The Dukes of Hazzard and sang the theme song.
