G Cadd9 Fadd9

[verse 1]
G (320003@1)           Cadd9You (x32030@1)would not believe your eyes
Fadd9
If ten million fireflies
G (320003@1)        Cadd9 (x32030@1)         Fadd9Lit (135211@1)up the world as I fell asleep

G (320003@1)                    Cadd9'Cause (x32030@1)they'd fill the open air
Fadd9
And leave teardrops everywhere
      G (320003@1)      
You'd think me rude
    Cadd9 (x32030@1)                Fadd9But (135211@1)I would just stand and stare

[chorus]
Fadd9 (135211@1)     G (320003@1)         DI'd (xx0232@1)like to make myself believe

     Fadd9 (135211@1)              GIt's (320003@1)hard to say that I'd rather stay
Em7            Cadd9Awake (x32030@1)when I'm asleep
       Fadd9 (135211@1)       G (320003@1)         D'Cause (xx0232@1)everything is never as it seems

[verse 2]
G (320003@1)              Cadd9'Cause (x32030@1)I'd get a thousand hugs
Fadd9
From ten thousand lightning bugs
G (320003@1)              Cadd9 (x32030@1)         Fadd9As (135211@1)they tried to teach me how to dance

G (320003@1)        Cadd9 (x32030@1)  
A fox trot above my head
Fadd9
A sock hop beneath my bed
  G (320003@1)               Cadd9 (x32030@1)           Fadd9A (135211@1)disco ball that's just hanging by a thread

[bridge]
G (320003@1)           Cadd9 (x32030@1)     Fadd9Leave (135211@1)my door open just a crack
(Please take me away from here)
G (320003@1)                Cadd9 (x32030@1)        Fadd9'Cause (135211@1)I feel like such an insomniac

G (320003@1)            Cadd9To (x32030@1)ten million fireflies
Fadd9

G (320003@1)         Cadd9 (x32030@1)           Fadd9I (135211@1)got misty eyes as they said farewell

G (320003@1)                 Cadd9But (x32030@1)I'll know where several are
Fadd9
If my dreams get real bizarre
       G (320003@1)               Cadd9 (x32030@1)          Fadd9'Cause (135211@1)I saved a few and I keep them in a jar
