On the original release solely credited to Junior Parker and published by Memphis Music. By the time Elvis Presley recorded it, Sam Phillips had added his name to the copyright (possibly as part of a settlement of Parker's contract dispute with Sun Records) and the publishing had been transferred to Phillips' Hi-Lo Music.
