The legendary musician Willie Nelson appeared on Comedy Central's The Daily Show Tuesday night to promote his memoir It's a Long Story: My Life that just released.

Nelson recently turned 82 at the end of April and has put out quite a few books, dating back to 1988. He also has put out nearly 70 studio albums, plus more music through live albums, soundtracks and compilations. Plus, he is known for writing hits for other artists too.

As The Daily Show's host Jon Stewart said, Nelson's been "putting out the most prolific music; different styles."

Stewart mentioned how the musician began writing songs at the very young age of 7, but Nelson shared, "I started writing poems around then."

He further explained that once he learned how to play guitar, he began to add in melodies to the poems.

"I never had a problem writing the songs," Nelson said, adding, "Were they good or not? I don't know. Writing a song wasn't hard work."

Nelson then shared some insight on how a songwriter's relationship is with a publishing company.

"Well, a writer normally if he writes for a publishing company he gets x-amount of dollars for every record that is sold so Patsy Cline's 'Crazy' did very well so it made some money," Nelson revealed.

Nelson is up there in age, but he still tours quite a bit and thoroughly enjoys it.

"I still enjoy playing music. As long as the people show up to hear it, I hope to stay out there," Nelson shared.

His memoir sheds depth on his entire life.
