the begining of the song a piano is playing to me it sounds like G and Bm. 

Verse 1:

G                   Em                         Bm
Hands over my head thinking what else could go wrong?
G                   Em                      Bm
Wouldve stayed in bed, how can a day be so long?
Em                  C                   G    D/Fbass
Never believed that things happen for a reason
Em                       C                          G     
But how this turned out, you moved all my doubts, I believe 
D/Fbass
That for you Ill do it

Chorus:

C        Em
All over again
          C    Em         
Do it all over again
           Am                 Em 
All I went through, led me to you
                D
So Id do it all over again 

For you

G Bm

Verse 2:
G                         Em                          Bm
I missed the first train, stood out in the rain, all day

G                             Em                           Bm 
When I caught the next train, there you were to sweep me away
 
Guess thats what Ive waited for
Em                  C                     G     D/Fbass 
Never believed that things happened for a reason
Em                           C                    G  
But how this turned out, you moved all my doubts, I believe

That for you Ill do it

All over again
          C    Em
