OK now I'm on a mission to find Marlboro songs :) : -
The Paula Cole song "Where Have All the Cowboys Gone?" features the verse "Where is my Marlboro Man?".
The Harvey Danger song "Sad Sweetheart of the Rodeo" features the sarcastic verse: "The Marlboro Man died of cancer/And he wasn't a rocket scientist when he was healthy/ha ha ha".
The Jason Aldean song "Dirt Road Anthem" references "The king in the can and the Marlboro man"
