     The intro consists of just playing alternating G and C major chords.
     For the pattern, just listen to the song.  Here's the main part.  As
     this is the first time I've tried to notate something like this on a
     computer, please forgive the clutter.

     If you didn't care


                      G      Gsus4      G
     what happened to me


                  C          Csus4      C
     And I didn't care

     For you.                    We would zig-zag our way


                 A7                     G              C
     Through the boredom and pain.      Occasionally   glancing


   D              G      Am             F                 Am         F
   up through the rain       Wondering       which of the buggers to blame


     C    Am7/B   Am         D        Dsus4   D               G
                         And watching         for pigs on the wing.
