Johnny Cash: I think the first time I knew what I wanted to do with my life was when I was about four years old.  I was listening to an old Victrola, playing a railroad song.  The song was called “Hobo Bill’s Last Ride.”  And I thought that was the most wonderful, amazing thing that I’d ever seen.  That you could take this piece of wax, and music would come out of that box. From that day on, I wanted to sing on the radio. That was the big thing when I was growing up, singing on the radio. The extent of my dream was to sing on the radio station in Memphis.  Even when I got out of the Air Force in 1954, I came right back to Memphis and started knocking on doors at the radio station.
