In the first half of the century, the biggest songwriters were often rags-to-riches Tin Pan Alley veterans, often immediately descended from New York City immigrants. Cole Porter was out of place in this world, being a professionally educated Midwesterner born into a large amount of money. All the same, he composed some of the smartest, sexiest, most suavely sophisticated songs around. In Porter songs, love is often a sort of bittersweet addiction—something that can be wrestled with, but never beaten. The two songs we just heard demonstrate this well. While “I get a kick out of you” was written for his Broadway hit “Anything Goes,” “I’ve got you under my skin” was written directly for the silver screen, for the 1936 musical “Born to Dance,” starring Eleanor Powell and Jimmy Stewart.
