Knowing your emotions are shaped by songs you heard 50 years ago is a little troubling. It makes you wonder whether your emotions are really yours or whether they are really Irving Berlin's set down with music to make a buck. It makes you wonder who is the real you. As my Aunt Gertrude used to say about Oakland, there's no there there; and maybe there's no real you in your emotions either.
But I don't believe that. When I say, "I've got the sun in the morning and the moon at night," there's a big dose of Ethel Merman but also some of me.
