John R. Cash is the 51st overall album by country singer Johnny Cash, released in 1975 on Columbia Records. It consists mostly of covers of other musicians' songs. The first track on the album, a song titled "My Old Kentucky Home", is not the state song of Kentucky, but a composition by Randy Newman which had been previously recorded by the Osborne Brothers in 1970 and Three Dog Night in 1972; Cash's version, like that of the Osborne Brothers five years previous, was released as the second single from the album, though the previously issued single "The Lady Came from Baltimore" had achieved greater success on the charts, reaching #14. The Cash original "Lonesome to the Bone" had previously appeared on Ragged Old Flag (1974) and would make one more appearance on Silver (1979).
Cash himself disliked John R. Cash, criticizing both the album, and its production process, in his 1997 autobiography, Cash: The Autobiography. He claimed the release was "[the CBS bosses'] idea of an album to restore [Cash's] sales potential", mentioning that the instrumental tracks were recorded separately from the vocals.
