Bill {Black} 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.
Elvis‘ version became a huge hit and helped to introduce him to radio audiences. {Along with That’s All Right}.
