Joey Scarbury believe it or not theme from greatest american hero

Look at what's happened to me.
i can't believe it myself.
suddenly i'm on top of the world,
it should've been someone else.
Believe it or not,
i'm walking on air.
i never thought i could feel so free- eee-eee.
flying away on a wing and a prayer,
who could it be?
believe it or not it's just me.
It's like a light of a new day,
it came out of the blue.
breaking me out of the spell i was in,
making all of my dreams come true-ue- ue.
Look at what's happened to me.
i can't believe it myself.
suddenly i'm up on top of the world,
it should've been somone else.
