Ethel Waters introduced "Stormy Weather," written by Ted Koehler & Harold Arlen, in the 1933 "Cotton Club Parade." She was accompanied by Duke Ellington's Orchestra. The song was a hit, and it was recorded by Waters (for Columbia), Ellington (Brunswick) and even composer Arlen for Victor Records. All were issued contemporaneously, along with at least a dozen more versions in the USA and UK. They weren't covers in the sense we think of them today; the song was the thing.
