Well, let's try:

  FIELDS OF ATHENRY
  
       G                     C                  G   D7 
  By a lonely prison wall, I heard a young girl calling 
   G                  C          D7
  "Michael, they have taken you away,
          G                 C
  For you stole Trevelyan's corn,
         G                   D7
  So the young might see the morn.
        D7                              G
  Now a prison ship lies waiting in the bay."
  
    G
    Low lie the fields of Athenry
          G                                    D7
    Where once we watched the small free birds fly
        G               C
    Our love was on the wing
           G                   D7
    We had dreams and songs to sing
            D7                              G
    It's so lonely round the fields of Athenry.
  

This is a simple arrangement in G. Obviously, the song can be transposed into a range comfortable for your voice.
