On January 13, 1968, Johnny Cash recorded his 27th album At Folsom Prison live at Folsom State Prison.  Some of my favorite songs on the album: “Long Black Veil”, “Folsom Prison Blues”, “Orange Blossom Special” and “Green, Green Grass of Home”. Cash had been interested in this particular prison for over a decade by the time he made At Folsom Prison!  In 1951, he watched the film Inside the Walls of Folsom Prison and it inspired him to write his 1955 hit “Folsom Prison Blues”.
