About "Volare (Nel Blu, DiPinto Di Blu)" — "To Fly (In Blue, Painted Blue") — he writes:
You get the mental picture, Utopia, and it’s painted blue. Oil paint, cosmetics and greasepaint, frescoes with blue slapped on, and you’re singing like a canary. You’re tickled pink and walking on air, and there’s no end to space.... Supposedly it’s about a man who wants to paint himself blue and then fly away. Volare, it means, “Let’s fly away into the cielo infinito.” Obviously, the endless sky. The entire world can disappear but I’m in my own head.
About "Blue Suede Shoes":
These shoes are not like other shifty things that perish or change or transform themselves. They symbolize church and state, and have the substance of the universe in them, nothing benefits me more than my shoes.... They neither move nor speak, yet they vibrate with life, and contain the infinite power of the sun. They’re as good as the day I found them. Perhaps you’ve heard of them, blue suede shoes. They’re blue, royal blue. Not low down in the dumps blue, they’re killer blue, like the moon is blue, they’re precious. Don’t try to suffocate their spirit, try to be a saint, try to stay as far away from them as you possibly can.
