Was listening to Billy Joel and thought his 'I go to extremes' is a fitting theme song for Clark/superman. Check out the lyrics:
Copyright Billy Joel
Too high or too low there ain't no in-betweens
You can be sure when I'm gone
I won't be out there too long
Darling I don't know why I go to extremes
Out of the darkness, into the light
Leaving the scene of the crime
Either I'm wrong or I'm perfectly right every time
Sometimes I lie awake, night after night
Coming apart at the seams
Eager to please, ready to fight
Why do I go to extremes?
Reach for the moon, for even if you fail, you'll still land among the stars... and who knows? Maybe you'll meet Superman along the way.
