When you think Singing in the Rain you probably think of the Gene Kelly movie. But the song itself is much older. It goes all the way back to the mid-’20’s—a few years before the dramatic date of the movie, appropriately enough.
Today’s trivia: Popular mythology says that the instant The Jazz Singer came out, in late 1927, movie studios scrambled to add sound to everything in sight, whether planned or already in production. In fact the reaction was more like "Oh, hm, now that’s interesting” —and then they went calmly back to making silents for about another year and a half. And then suddenly in 1929 the delayed reaction set in and it was nothing but talkies from then on. Nothing like color, which coexisted peacefully with black-and-white for a couple of decades.
