Bo Duke is going country ... again. John Schneider was spotted in Nashville this week, playing two shows Wednesday night in downtown Music City, where he's apparently trying to relaunch his music career.

Though he's best known for his role on the hit TV series 'Dukes of Hazzard,' John has also had his share of country music success. He has recorded ten albums and scored several Top 10 hits back in the '80s, including 'It's Now or Never,' 'I've Been Around Enough to Know,' 'At the Sound of the Tone' and 'Country Girls.' But it's been almost two decades since he's released new music, so why the resurgence now? Well, it's all about a piece of advice given to him by Johnny Cash.

"Johnny told me that one day, you're gonna get back in the music and one day you're gonna hear a song that you will have to record. And that's the song that will bring you back into country music," John tells Music City TV. "He said, I don't know what it is and I don't know when you're gonna hear it, but when you hear it, you'll know."

That song that struck a chord with the actor/singer is called 'The Promise,' which John explains is a timely song that grabbed his attention and that he believes is the song "that Johnny Cash talked to me about all those years ago."

John actually lived with Johnny and June Cash for a while, when he was just starting his career. In addition to great musical advice, he also credits the couple for strengthening his Christian beliefs.
