I was standing in the wings behind the piano when Duke first played it ("Creole Love Call"). I started humming along with the band. He stopped the number and came over to me and said, "That's just what I was looking for. Can you do it again?" I said, "I can't, because I don't know what I was doing." He begged me to try. Anyway, I did, and sang this counter melody, and he was delighted and said "Addie, you're going to record this with the band." A couple of days later I did.
