Elvis Presley "Blue Moon of Kentucky" 1954 Sun Records 209 78 Single - This 78 RPM 10-inch single is a rare example of an Elvis Presley recording on Sun Records, featuring Elvis' songs "Blue Moon of Kentucky" and "That's All Right". Identified as Sun 209, the song was famously recorded and released only weeks later in the whirlwind that was the beginning of Elvis' storied career. The legend started here, as this was Elvis' very first single on Sun Records. The two sides showed a secret of the Elvis' greatness, the variety of his influences, as one side was an Arthur Crudup R&B classic, the other a Bill Monroe Bluegrass classic. While Elvis' Sun 45s are highly collectible, the Sun 78s are even more rare and desirable.
