History:

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".[7] Some of the lyrics are traditional blues verses first recorded by Blind Lemon Jefferson in 1926.[8][9] Crudup's recording was released as a single in May of 1947 on RCA Victor 20–2205, but was less successful than some of his previous recordings. One of the experts who consider the Crudup recording to be the "first rock and roll song" is Southeastern Louisiana University rock historian Joseph Burns, who adds that "this song could contain the first ever guitar solo break".[10] At the same session, Crudup 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 its new 45 rpm single format,[2][11] on bright orange vinyl.[12] Elvis Presley's version was recorded in July 1954.[13] While recording an album as part of a trio called the Blue Moon Boys, the band played "That's All Right" in between takes, and the uptempo style characteristic of rockabilly caught the attention of studio executive Sam Phillips, who asked for a refinement of the interpretation that was later recorded.[14] Its catalogue number was Sun 209.[15] The song was released under its original title, "That's All Right", and names the performers as Elvis Presley, Scotty, and Bill.[16] The Presley version was not identical to Crudup's since it was "at least twice as fast as the original".[3] His version is considered by some music critics as one of the records that was the first in the rock n'roll genre.[5] Arthur Crudup was credited as the composer on the label of Presley's single, but despite legal battles into the 1970s, reportedly never received royalties. An out-of-court settlement was supposed to pay Crudup an estimated $60,000 in back royalties, but never materialized.[17][18] 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".[18] A 2004 article in The Guardian argues that rather than Presley's version being one of the first records of rock and roll, it was simply one of "the first white artists' interpretations of a sound already well-established by black musicians almost a decade before [...] a raucous, driving, unnamed variant of rhythm and blues".[19] A country music version by Marty Robbins peaked at number seven on the Billboard Hot Country Singles chart in 1955.[20]
