[Intro]
G      C
[Estrofa]
G             C         Cadd4      C 
If you didn't care 
                 G      Csus2      G 
what happened to me 
             C          Cadd4      C 
And I didn't care 
     G       Csus2     G 
For you 
            A              G*   A   G* 
We would zig-zag our way 
            A7 
Through the boredom and pain  
G              C           D            G 
 Occasionally   glancing   up  through  the rain 
Am               F                Am        F         C    C/B   Am 
     Wondering      which of the buggers to blame 
        D      Dsus4   D               G 
 And watching          for pigs on the wing
