Elvis Presley — That’s All Right (1954)
“That’s All Right” was recorded by The King of Rock ‘n’ Roll as they took a break from a day of recording. He simply started jamming to Arthur Crudup’s “That’s All Right, Mama.” When Sam Phillips heard it, he was interested. He pressed record and put “Blue Moon of Kentucky” on the B-side. The rest, as they say, is history. Many people even claim it is the first true record of rock ‘n’ roll. Have you got this one in mint condition? You can fetch about $4,000 for it if this is the case.
