As one of the first and biggest guest stars on the series, Johnny Cash would reprise his role four times during Dr. Quinn Medicine Woman's six-season run, portraying Kid Cole, former gunslinger turned law-abiding sheriff.

Cash would continue to reprise his role on the series because of his growing friendship with Jane Seymour on and off the screen. Following the series, Seymour would go on to name her son after him and her at-the-time husband, John Keach, would even produce Cash's biopic, Walk The Line. 

The Man in Black would even get his beloved friends and family involved in the series as well. Along with him was his wife, June Cash, who played his love interest and Bob Wootton, lead guitarist of his backing band, The Tennessee Three.

Bob was a life-long fan and friend who first met Johnny Cash in 1970, when Cash needed a quick lead guitarist for a performance in Arkansas. Bob, being such a big fan of Cash, played all his famous songs with ease and would be invited to become a permanent member as the lead guitarist for The Tennessee Three and Johnny Cash. 

When filming for Dr. Quinn, Bob Wootton would back up Johnny Cash once again — but this time as his stunt double. Anytime Kid Cole needed to be filmed on a horse, Wootton was used instead due to Cash's life long fear of horses. Along with snakes and flying, Johnny Cash's fear of horses required some Hollywood magic anytime Kid Cole had to ride off into the sunset.
