20. York Out
Producers and the show never bothered to explain why York left. It worked out in the end, but York had good reason to leave. In the late ’50s, he was in a film called “They Came to Cordura.” During the filming of that movie, he tore a bunch of muscles in his back. Doctors prescribed the usual, pain medication. In the long run, the regimen of pills and pain was too much. As is often the case, York found himself addicted to those meds in later years. He left the show before it affected his performance.
