The unvarnished and complete story of the life of one of America's greatest ever songwriters.

Five decades in the music industry, 100 albums, 10 Grammys, the Kennedy Center Honors, and the Country Music Hall of Fame. Add high-profile activism for the legalisation of marijuana, the foundation of a ground-breaking philanthropic organisation, and a much-publicised personal life - Willie Nelson's is a story like no other.

Born during the great depression in 1933 and raised by his grandparents, he began singing in dance halls and Honky Tonks at the age of 13, as an escape from working as a cotton picker in the fields of Arkansas. He went on to write some of the most popular country songs of all time, and to record some classic versions of others, including Crazy, Bring Me Sunshine, Always on my Mind and Blue Eyes Crying in the Rain. An American icon who still tours extensively and headlines music festivals, Willie Nelson and his music have found their way into the hearts and minds of fans all over the world.

Now 81 years of age, Nelson leaves no experience or moment unturned as he shares the full story. From his drive to write music to the women in his life; from his collaborations to his bankruptcy to the foundation of Farm Aid; Nelson shares, in his distinct voice, soaring highs and painful lows.
