In 1970, LeDoux became a professional rodeo cowboy, competing on the national rodeo circuit. To help pay his expenses while traveling the country, he began composing songs describing his lifestyle. Within two years, he had written enough songs to make up an album, and soon established a recording company, American Cowboy Songs, with his father. After recording his songs in a friend’s basement, LeDoux began selling his albums out of the back of his truck at rodeo events.
In August 2000, LeDoux was diagnosed with primary sclerosing cholangitis, which required him to receive a liver transplant. Garth Brooks volunteered to donate part of his liver, but it was incompatible. An alternative donor was located, and LeDoux received a transplant on October 7, 2000. After his recovery he released two additional albums. In November 2004, LeDoux was diagnosed with cholangiocarcinoma for which he underwent radiation treatment until his death on March 9, 2005 from the cancer. He was survived by his wife of 33 years, Peggy, and their children Clay, Ned, Will, Beau, and Cindy, as well as his mother, Bonnie.
Shortly after his death, LeDoux was named as one of six former rodeo cowboys to be inducted into the ProRodeo Hall of Fame in Colorado Springs in 2005. He was the first person to ever be inducted in two categories, for his bareback riding and in the “notables” category for his contributions to the sport through music.
