Cash wrote "I Still Miss Someone" with his nephew, Roy Cash Jr. He performed "I Still Miss Someone" At Folsom Prison, and most of Cash's live recordings after the 1960s also included this song.
Cash appeared in Eat the Document, which documented Bob Dylan's 1966 world tour, performing "I Still Miss Someone" with Dylan backstage. Cash later recorded the song as a duet with Dylan during sessions for Dylan's album Nashville Skyline in 1969; however, this duet has never been officially released.
Jimmy Buffett performed the song as a dedication to Cash at the White River Amphitheatre in Auburn, Washington on September 16, 2003, four days after Cash's death. Before playing it, Buffett said it was his favorite Johnny Cash song. It's the only time Buffett ever played the song, and the performance was recorded and released on the live albumLive in Auburn, WA. Also Gram Parsons And the International Submarine band covered it on their only album.
