Intro: C G C G
Em          C
Everybody loves to tell me
G
I was born an old soul
Em             C
But I keep my eyes wide open
G
There's so much that I don't know
Em             C
Just another hotel room
G
Never felt so all alone
Em                   C
I think about my granddad's eyes
G
And they're always sending me home
C G
   I can almost hear him now
C G
   I gotta make him proud
          Em** C**   G
I keep my eyes wide open
           Em**  C**   G
Left this ground unbroken
Em            C
I'm about to make it my way
G
Heaven on me, keep my faith
   Em** C**   G
My eyes wide open
C G C G
Em                C
I can't see two steps ahead of me
G
When the fog comes rolling in
Em                    C
I never thought I'll miss the rain
G

 Yeah, an instant
