Intro: ||: F ? C/E ? Dm | Dm ? C ? Bb | Bb ? C/A ? Gm | C :||

   F     C/E    Dm      
Do you remember me
   Dm  C                Bb
I sat upon your knee
  Bb            F/A        Gm                   C       
I wrote to you with childhood fantasies
        F        C/E        Dm
Well I?m all grown up now
    Dm    C             Bb
Can you still help somehow?
    Bb  F/A        Gm                           C
I?m not a child, but my heart still can dream
   F             C/E            Dm
So here?s my lifelong wish
   Dm       C           Bb
My grown up Christmas list
    Bb  F/A       Gm                    C
Not for myself, but for a world in need


Chorus:
D         bm       G
No more lives torn apart
     G/E        A       f#m
That wars would never start
    bm         A        G       A       
And time would heal all hearts
D     bm                G
Every man would have a friend
        G/E             A       f#m
That right would always win
        bm              A        g#dim7
And love would never end
f#m  bm em              A       D ? Dsus - D 
This is my grown up Christmas list


Bridge:
D                                               G       
What is this illusion called the innocence of youth?
        bm               E
Maybe only in that blind belief
          A                 C#  
Can we ever find the truth...
