The song goes as follows as close as I can figure:

  G-G-D-D-with a hammer on the high E string with the pinkie
  You wi**h , You w**h...
  G-C-Am-D

  G--D--same Hammer on
  If I c*n't g*t thru...
  G-C-Am-D

  Chorus:G-G-D-D

         G-G-D-D

         C-C-D-D

         G and play around with the ring finger on the A string
           then go to---D

         G same A string then D

          when done with chorus fall to D-C-then a pause then start
