From the wiki: “First published as ‘I’ve Got The Love-sick Blues’ and introduced by Vaudeville singer Anna Chandler in the musical Oh, Ernest, ‘Lovesick Blues’ was first recorded by Elsie Clark in a March 1922 for OKeh Records, then was covered by Jack Shea for Vocalion Records later the same year. In 1928, ‘Lovesick Blues’ was covered by Emmet Miller (accompanied by his ‘Georgia Crackers’, including Tommy Dorsey, Jimmy Dorsey, Eddie Lang, and Leo McConville) and, in 1939, by country singer Rex Griffin.
“The recordings by Miller and Griffin would inspire Hank Williams to perform the song during his first appearances on The Louisiana Hayride in 1948. Receiving an enthusiastic reception by the audience, Williams decided to record his own version despite an initial push-back from his band and his producer, Fred Rose.
