I remember your bare feet down the hallway

I remember your little laugh
                 Dbm 
Race cars on the kitchen floor
        A            B                         E   - Intro part - Dbm  A  B

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
                     Dbm 
I can still feel you hold my hand
A           B                       E 
Little man, from even that moment I knew
                           Dbm 
You fought it hard like an army guy
  A                      B 
Remember I leaned in and whispered to you

Chorus:
A                  B 
Come on baby with me
                    E      A 
We're gonna fly away from here

You were my best four years

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

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

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

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

Come on baby with me

We're gonna fly away from here

I love you to the moon and back
