I met Johnny Cash in college at a concert in Las Cruces, NM. I was attending NMSU and worked in the maintenance department. I worked the concert and snuck back to the hallway leading to his dressing room. A lone figure walked toward me and I figured it was his security and my gig would be up. But, to my elation it was non other than JC himself. We exchanged hello's and I asked if he would play Rock Island Line. I must have been excited and spoke way too fast. He asked me to repeat myself 3 times. Finally he just put his index finger up and said, "Well, allllright!". It was awesome!
