Verse:
C               Am                 F 
I remember your bare feet down the hallway
  G                    C 
I remember your little laugh
                 Am 
Race cars on the kitchen floor
        F            G                         C   - Intro part - Am  F  G 
Plastic dinosaurs, I love you to the moon and back

Verse
C               Am                F                 G                  C 
I remember your blue eyes looking into mine like we had our own secret club
               Am             F             G                       C 
I remember you dancing before bed time then jumping on me waking me up
                     Am 
I can still feel you hold my hand
F           G                       C 
Little man, from even that moment I knew
                           Am 
You fought it hard like an army guy
  F                      G 
Remember I leaned in and whispered to you

Chorus:
F                  G 
Come on baby with me
                    C      F 
We're gonna fly away from here
    F       G          C     Am  F  G 
You were my best four years

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

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

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

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

Chorus:
- F -               G 
Come on baby with me
                   C       F 
We're gonna fly away from here
                  G 
Come on baby with me
                   C       F 
We're gonna fly away from here
    F       G         C 
You were my best four years

Outro:
C               Am                 F 
I remember your bare feet down the hallway
  G                        C 
I love you to the moon and back
