Nelson and Kristofferson formed The Highwaymen with fellow country superstars Johnny Cash and Waylon Jennings in 1985. The supergroup's debut album, "Highwayman," topped Billboard's Top Country Albums chart, while the title track became a No. 1 hit.

The band also brought their country chemistry to the tube, starring in the Western TV film "Stagecoach" in 1986.

Following their sophomore album "Highwayman 2" in 1990, The Highwaymen released their final album, "The Road Goes on Forever," in 1995.

"He was a great songwriter," Nelson told AP of Kristofferson. "He left a lot of fantastic songs around for the rest of us to sing, for as long as we're here."
