Piano, but I do this on acoustic so it pretty much rocks still, for a ballad.

G                              D
Moonlight eyes I see you smile, it lightens up my night
     Am                D           G
Your smile takes all the fight, out of me
G                                 D
Moonlight eyes I hear your crying, it robs me of my pride
       Am            D                G
There's nothing I can hide from moonlight eyes
      D                 C                G
I got no control you just roll me, like the sea
           D
Oh moonlight eyes!
G                                D
Moonlight eyes you've grown now, I'll soon be out of touch
       Am             D                G
You'll lose that innocence that cost so much!
G                                    D
And moonlight eyes, you'll find your pain say that I'm all wrong,
       Am           D                G
They'll always be a place where you belong

(Speed up the tempo a bit)
     D                   C               G
I got no control, you just roll me like the sea
             D                 C
Oh moonlight eyes, tell your sweet lies
      G
Only to me
      D
Only to me
C                D
Moonlight eyes you sooth me
C               D              G        D
Moonlight eyes you're easy on my sooooooooooul

Moonlight eyes you are the reason, the meaning to the words
The words to every song I ever loved
Paralysed in sweet suprise, every wrong is right
One look into your night, oh Moonlight eyes
I got no control you just roll me like the sea
Oh moonlight eyes, tell your sweet lies
Only to me
Only to me
Moonlight eyes!
