Okay so this is the whole song. I apologize for any typos. I hope this helps but 
you still have to figure the strumming out on your own ;D

Intro (F, C, G) 
                F                                        C        G
Verse 1: We should get jerseys, 'cause we make a good team
          F                                                      C                  G
But yours would look better than mines 'cause you're out of my league 
           F                    
And I know that it's so cliche 
    C                                             G       
to tell you that everyday I spend with you is the new best day of my life
         F  
And everyone watching us
          C
Just turns away with disgust  
                 G
'Cause jealously they can see that we've got it going on
                                           F                                  
Pre-Chorus: And I'm racking my brain for a new improved way
                     C                                  G
To let you know you're more to me than what I know how to say
  F                                      C
You're okay with the way this is going to be
                                          G
'Cause this is going to be the best thing we've ever seen
                     C                      G                      C                     G       
Chorus: If anyone could make me a better person you could
Bb             F               Bb                          F       
All I gotta say is I must have done something good
          C                           G                     C                 F 
You came along one day and you rearranged my life
Bb               F               Bb                        F                G
All I gotta say is I must have done something right

I must have done something right.

Fill (F, C, G)

Verse 2: Maybe I'm just lucky, 'cause it's hard to believe
Believe that somebody like you'd end up with someone like me
And I know that it's so cliche to talk about you this way
But I'll push all my inhibitions aside
It's so very obvious to everyone watching us 
That we have got something real go going on

(Pre-Chorus)
(Chorus)

Bridge: (The bridge is just ba ba ba ba ba. So just play C, G, A#, F just like 
the chorus and match them with he 'ba's.)
