to rehearse and record a handful of songs. According to Moore, the first song they recorded was "I Love You Because", but after a few country music songs that weren't impressive they decided to take a break. During the break, Presley began "acting the fool" with Arthur Crudup's "That's All Right (Mama)," a blues song. When the other two musicians joined in, Phillips taped the song. The upbeat sound was original. Black remarked, "Damn. Get that on the radio and they'll run us out of town." The next day, the group recorded four more songs, including “Blue Moon of Kentucky," by the bluegrass musician Bill Monroe, which he had written and recorded as a slow waltz. Sources credit Black with initiating the song, with Presley and Moore joining in. Moore said, "Bill is the one who came up with "Blue Moon of Kentucky." ... We're taking a little break and he starts beating on the bass and singing "Blue Moon of Kentucky," mocking Bill Monroe, singing the high falsetto voice. Elvis joins in with him, starts playing and singing along with him ..." They ended up with a fast version of the song in 4/4 time. After an early take, Phillips can be heard on tape saying, "Fine, man. Hell, that’s different—that's a pop song now, nearly ʼbout." Phillips took several acetates of the session to DJ Dewey Phillips (no relation) of Memphis radio station WHBQ's Red, Hot and Blue show. From August 18 through December 8, "Blue Moon of Kentucky" was consistently higher on the charts, and then both sides began to chart across the South. Black and Moore became Presley's backup group and were paid 25% of his earnings. Moore and Black left the Starlite Wranglers after the success of "That's All Right," jealousy within the group forcing them to split. Their recordings at Sun were released with the credits as "Elvis Presley, Scotty and Bill." The group was later billed as "Elvis Presley and the Blue Moon Boys." Over the next 15 months, the trio released five singles, toured across the South, and appeared regularly on the Louisiana Hayride. They had auditioned for the Grand Ole Opry in October 1954, but they failed to impress the people in charge, or the audience, and were not invited back. In 1955, Black went to RCA Victor along with Presley and Moore when Presley's contract was sold to that company.
