Sully Erna - Until Then chords

This is a beautiful song done on piano, with a nice intro that I do not have
tabbed. Each chord in the intro is one bar except the D and F after the Eb. 
Thank You and Enjoy

Gm
Lie, awake, Watching you run through my head
     F
I'm alone again
            Gm
But not for long my friend, We face another day
                                         F
And distance has come, and taken you far away again
                 Gm
But I'll see you soon my friend
                          Gm   Gm   F   F
And then I'll sing you my song

  Gm
I can't
         F
Go home alone again
     Eb        D   F
No I can't, my friend
      Gm
Until then

Gm
Eyes, I recognize, Taking me back
                        F        
Familiar to me from some other time
         Gm
Or maybe another life, Remember our times, and know who I am
                                          F
The memory stays, until we can breathe as one again
               Gm
And I'm coming back my friend
                          Gm   Gm   F   F
And then I'll sing you my song      Oh-oh yeah

      Gm
And I can't
         F
Go home alone again
     Gm
No I can't
             F
Go home all alone again
     Gm
No I can't
             F
Go home all alone again
     Eb        D  F
No I can't, my friend
      Gm
Until then
