"Richards was certainly no stranger to country music when he met singer/songwriter Gram Parsons in the late 1960s, as evidenced by the unreleased documentary, "Charlie Is My Darling." In its footage that was recording during the Stones' 1965 Irish tour, Mick Jagger is seen singing Hank Williams' "I'm So Lonesome I Could Cry," as Richards accompanies him on keyboards. Another country track that was recorded by the Stones was the late Hank Snow's "I'm Movin' On," which appeared on the 1965 release, December's Children."
