A few parts of the lyrics are questionable, I couldn't find official ones.  The chords are right though.

That Em to Em/Eb in the chorus is done thusly:

7 to 7
8    8
9    9    
9    9

Verse 1: 
G5                      B5
Give me a minute to compose myself, it?s been
E5                    C5
Long, long time since you been gone
G5                           E5
I can still remember conversations we had
    D5                   C5
too bad that?s all that now lingers on
G5                      B5
So many times I nearly fooled myself that some?
E5                         C5
Body like you could give a damn about me
G5                              E5
But then one day you stepped into my life,
          D5               G5  
All my strife was a fleeting memory

Chorus:
C5                   E5      D5                C5
Over and over in my head at night (What went wrong?)
C5                                   E5     E5            C5
Didn?t lose the battle, didn?t give up the fight (What went wrong?)
C5                         E5          D5                C5
To let you go then didn?t make things right (What went wrong?)
C (speed up strumming)                     Cm
Can?t hide the tears from my eyes now that love?s gone and passed me by?

Verse 2: 
G5                        B5
During my life I somehow steered you wrong
E5                                   C5
From the road once again was driving us way
G5                              E5
I pushed aside the things that meant so much
     D5                  C5             
With hope that you?d be happy some day
G5                          B5
I wear regret now like the lines on my face
E5                                 C5
Not a day passes on that you don?t cross my mind (You don?t cross my mind?)
G5                               E5
Couldn?t raise the spirits of a broken heart
         D5                              G5 
And chance the ?

Chorus

C5                   E5      D5                C5
Over and over in my head at night (What went wrong?)
C5                                   E5     E5            C5
Didn?t lose the battle, didn?t give up the fight (What went wrong?)
C5                         E5          D5                C5
To let you go then didn?t make things right (What went wrong?)
C (speed up strumming)                     Cm
Can?t hide the tears from my eyes now that love?s gone and passed me by?

Solo: One time through verse chords, once through chorus... 

C5                                           C5
Can?t hide the tears from my eyes now that love?s gone and passed me by?

Verse 3:
G5                        B5
But then one day I gathered up the nerve
E5                                   C5
To trip all of those waves I vowed not to cross
G5                              E5
In for this pain that flow deep down inside
     D5                  C5             
That still housed the dreams that all is not lost
G5                          B5
Upon the threshold I now made my ascent
E5                                 C5
towards the door I should close on one careless days
G5                               E5
Without a look, just pass them buzzer and in
         D5                              G5 
That your name, long gone, it faded away

Chorus:
C5                   E5      D5                C5
Over and over in my head at night (What went wrong?)
C5                                   E5     E5            C5
Didn?t lose the battle, didn?t give up the fight (What went wrong?)
C5                         E5          D5                C5
To let you go then didn?t make things right (What went wrong?)
C (speed up strumming)                     Cm
Can?t hide the tears from my eyes now that love?s gone and passed me by?
