If I was a superhero,

No suit of armour, just lay your head down on this heart of mine.

I'm just a man that wants to give you the world,
[C]                   [G]
So I'm gonna love you the best that I can.

Verse 2 (Second verse same as first)

I would step, inside your mind to see what's behind those eyes, 
take a look at what you're dreaming of, you're dreaming of, tonight.
And I can see the future girl, its you and me, that's right.
And all the things you've always wished upon, you've wished for all your life.

The entire outro is [D] [A] [C] [G]

The best that I can.
I'm gonna love you, I'm gonna love you yes I am.
I'm gonna love you, I'm gonna love you the best I can.
I'm just a man, I'm just the man for you.
I'm just the man for you.
