When I had talked to [creator] Bruce Timm about what vision did he have for the character. He said, "Well I don't want anything like John Williams always does, where you can go 'Superman' to the music." ...So I labored away at this thing, and I tried and tried and tried to get something...and he just wasn't happy with any of the stuff I was coming up with. Then I did what you frequently learn to do when people say they don't want something: go ahead and do exactly that! [sings Superman theme] "Superman...Superman...Da, dit, dit, DA, dit, dit, Superman!" And he just loved it.(That reminds me of the time I got to interview composer Michael Kamen. He mentioned the only theme in Brazil not based on a song was the theme for Tuttle the heroic repairman, and that he wrote it by simply singing Tuttle's name: "Tutt-llllle, Tutt-llllllllle...Harrrrr-y Tutt-llllle! A little idiotic, but such is life.")
