Something for the weekend. Missouri Waltz. Published in 1914, the melody was by John Valentine Eppel, arrangement by Frederic Knight Logan, with James Royce Shannon supplying the lyrics. Initially the song sold poorly, but its popularity increased over the years. After Harry Truman became President it became associated with him, and was played constantly when he appeared during his long uphill campaign throughout the nation in 1948. In 1949 Missouri adopted it as its state song.
