CAPO 1

Intro
C#m     Am      Em      B#m

Verse
C#m                  Am                 Em
I'm ten miles from town, and I just broke down
                 B#m                      C#m
Spitting out smoke on the side of the road
              Am                          Em
I'm out here alone, just trying to get home
B#m                                        C 
To tell you I was wrong, but you already know


Pre-Chorus
           Am                      C
Believe me I won't stop for nothin'
C            Am          B#m
To see you so I've started runnin'


Chorus
Am          Em
All that I'm after
 B#m             C#m
Is a life full of laughter
Am             Em           B#m   B#m
As long as I'm laughing with you
          Am            Em                B#m       C#m
And I think that all that still matters is love ever after
Am       B#m               C#m
After the life we've been through
         Am             B#m         C#m
'Cause I know there's no life after you


SMALL SOLO:

Verse
C#m              Am                      Em                       
The last time we talked, the night that I walked
             B#m                    C#m
Burns like a light in the back of my mind
              Am                   Em                 
I must've been high, to say you and I
                B#m                      C
weren't meant to be and just wasting my time


Pre-Chorus
           Am               C
Oh, why did I ever doubt you
C            Am           B#m
You know, I will die here without you


Chorus
Am          Em
All that I'm after
 B#m             C#m
Is a life full of laughter
Am             Em           B#m   B#m
As long as I'm laughing with you
          Am            Em                B#m       C#m
And I think that all that still matters is love ever after
Am       B#m               C#m
After the life we've been through
         Am             B#m         C#m
'Cause I know there's no life after you


Bridge
Dm                        Bb    
You and I, right or wrong, there's no other one
F                     C
After this time spent on
                            Dm                                         
It's hard to believe that a man with sight could be so blind
Bb                              F                     C
Thinkin' 'bout the better times, must've been outta my mind
C
So I'm running back to tell you


Chorus
Am          Em
All that I'm after
 B#m             C#m
Is a life full of laughter
Bb           Em              B#m
Without you God knows what I'd do, yeah
Am          Em
All that I'm after
 B#m             C#m
Is a life full of laughter
Am             Em           B#m   B#m
As long as I'm laughing with you
C#m
And I think that
          Am            Em                B#m       C#m
And I think that all that still matters is love ever after
Am       B#m               C#m
After the life we've been through
         Am             B#m         C#m
'Cause I know there's no life after you


Outro
Am                 Em            B#m
You know there's no life after you
Am                 Em            B#m
You know there's no life after you
Am                 Em            B#m
You know there's no life after you
Am            Em            B#m
