<P> In July 2004, exactly 50 years after its first issuing, the song was released as a CD single in the United Kingdom, where it debuted and peaked at Number 3 . </P> <P> The song was written by Arthur "Big Boy" Crudup, and originally recorded by him in Chicago on September 6, 1946, as "That's All Right". Some of the lyrics are traditional blues verses first recorded by Blind Lemon Jefferson in 1926 . Crudup's recording was released as a single on RCA Victor 20 - 2205, but was less successful than some of his previous recordings . At the same session, he recorded a virtually identical tune with different lyrics, "I Don't Know It", which was also released as a single (RCA Victor 20 - 2307). In early March 1949, the song was rereleased under the title "That's All Right, Mama" (RCA Victor 50 - 0000), which was issued as RCA's first rhythm and blues record on their new 45 rpm single format, on bright orange vinyl . </P> <P> Elvis Presley's version was recorded in July 1954 . Its catalogue number was Sun 209 . The label reads "That's All Right" (omitting "Mama" from the original title), and names the performers as Elvis Presley, Scotty and Bill . Arthur Crudup was credited as the composer on the label of Presley's single, but even after legal battles into the 1970s, was reportedly never paid royalties . An out - of - court settlement was supposed to pay Crudup an estimated $60,000 in back royalties, but never materialized . Crudup had used lines in his song that had been present in earlier blues recordings, including Blind Lemon Jefferson's 1926 song "That Black Snake Moan". </P> <P> A country music version by Marty Robbins peaked at number seven on the Billboard Hot Country Singles chart in 1955 . </P>
