Ever since FDR made it his campaign song in 1932 while running for office during the Great Depression, the unofficial anthem of the Democratic Party has been that Tin Pan Alley classic, "Happy Days are Here Again." But no matter how often the old Victor spun, it would not be until well after Roosevelt's death that happy days would be here again.
Like Hope and Change, "Happy Days are Here Again" was a blandly optimistic and non-specific promise that good times were coming. Someday the happy days would arrive, an appropriate enough sentiment for a song whose pivotal moment came in the movie "Chasing Rainbows" where it was sung to reassure a cuckolded husband who is threatening to kill himself. And in an even more appropriate bit of symbolism, the actual movie footage of that moment is as lost as the happy times.
