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!
