The life and artistry will be celebrated in Johnny Cash: American Rebel, a CMT documentary airing tomorrow night at 9 pm on the 12th anniversary of his death.

Eric Church, Willie Nelson, Merle Haggard, and more make appearances and give interviews in the documentary. We’ll find out that during the Korean War, Johnny was 18 and an Air Force morse code interpreter who would intercept and decipher Russian communications. And apparently his military paychecks paid for his first guitar.

Find out more about the “Man in Black” tomorrow night at 9 pm on CMT. Definitely something to DVR and keep. –Jim
