That's All Right Mama

"That's All Right" is a song written and originally performed by blues singer Arthur Crudup in 1946. He must have been surprised to see, if he ever did, that it is here credited to Bob Dylan, with 'Mama' added to the title!
The song is best known as the first single recorded by Elvis Presley on July 5, 1954, and released on July 19 with "Blue Moon of Kentucky" as the B-side. .
