Look up in the sky!

Have you ever noticed that the famous Superman theme by John Williams matches the also famous (spoken) words from the 1950's TV show?

dat da da da dah
(look up in the sky)
da da da
(it's a bird)
dat da da da dah
(it's a plane)
da da da!
(Superman!)

No reason at all, just a slow afternoon at the store.
