I remember your bare feet down the hallway
  A                    D 
I remember your little laugh
                 Bm 
Race cars on the kitchen floor
        G            A                         D   - Intro part - Bm  G  A

I remember your blue eyes looking into mine like we had our own secret club

I remember you dancing before bed time then jumping on me waking me up
                     Bm 
I can still feel you hold my hand
G           A                       D 
Little man, from even that moment I knew
                           Bm 
You fought it hard like an army guy
  G                      A 
Remember I leaned in and whispered to you

Chorus:
G                  A 
Come on baby with me

We're gonna fly away from here

You were my best four years

Verse:
D              Bm                  G 
I remember the drive home when the blind hope
          A                      D 
Turned to crying and screaming, "Why?"
                        Bm 
Flowers piled up in the worst way
             G                   A 
No one knows what to say about a beautiful boy who died

Verse:
D                    Bm 
And it's about to be Halloween
             G            A                        D 
You could be anything you wanted if you were still here
               Bm              G 
I remember the last day when I kissed your face
  A 
I whispered in your ear

Chorus:
G                  A 
Come on baby with me
                    D      G 
We're gonna fly away from here
G                      A                          D 
 Out of this curtained room in this hospital grey
                 G 
We'll just disappear
                  A 
Come on baby with me
                   D       G 
We're gonna fly away from here
    G       A         D 
You were my best four years

What if I'm standing in your closet trying to talk to you?
          G                A                    D 
What if I kept the hand me downs you won't grow into?
              G                   A             D 
And what if I really thought some miracle would see us through?
                G           A                G           A - once -
But what if the miracle was even getting one moment with you
