All of the versions currently up have had the wrong chords, so I thought I would edit it
put in the ones Dropkick Murphys used.  Enjoy!  All of the verses have the same chords. :)

        Intro:  Eb-Ab-Bb-Eb (all chords are three 
long)

          Eb (x43121@3)            Cm (x3101x@1)     Ab (xx1114@1)    Bb (x1333x@1)         Well how do you do young Willie McBride,
                 Bb (x1333x@1)       Bb (x1333x@1)          Ab (xx1114@1)         Eb (x43121@3)         Do you mind if I sit here down by your graveside,
                         Cm (x3101x@1)         Ab (xx1114@1)        Bb (x1333x@1)         And rest for a while in the warm summer sun,
                    Bb (x1333x@1)               Ab (xx1114@1)        Bb (x1333x@1)         I've been walking all day and I'm nearly done.
          Eb (x43121@3)           Cm (x3101x@1)                Fm (133111@1)         I see by your gravestone you were only 19,
                   Bb (x1333x@1)                      Ab (xx1114@1)name="chord_x1333x@1">Bb
          When you joined the great fallen in 1916,
               Eb (x43121@3)            Cm (x3101x@1)         Fm (133111@1)         Well I hope you died quick and I hope you died clean,
             Bb (x1333x@1)                 Ab (xx1114@1)      Eb (x43121@3)         Or Willie McBride was it slow and obscene.


          Chorus:

                   Bb (x1333x@1)         Did they beat the drum slowly,
	            Ab (xx1114@1)          Eb (x43121@3)  Did they play the fife lowly,
                   Bb (x1333x@1)                          Ab (xx1114@1)        Bb (x1333x@1)         Did they sound the death march, as they lowered you down,
                  Ab (xx1114@1)                         Eb (x43121@3)name="chord_x3101x@1">Cm
          Did the band play the last post and chorus,
                  Eb (x43121@3)            Ab (xx1114@1)           Bb (x1333x@1)Eb (x43121@3)         Did the pipes play the Flowers of the Forest.

          And did you leave a wife or a sweetheart behind,

          In some loyal heart is your memory enshrined,

          And though you died back in 1916,

          To that loyal heart  you're forever 19.

	  Or are you astranger (x02210@1)without even aname, (x02210@1)
          Forever enshrined behind some old glass pane,

          In an old photograph all torn tattered and stained,

          And faded to yellow in a brown leather frame.


          Chorus


          The sun's shining down on these green fields of France,

          The warm wind blows gently and the red poppies dance,

          The trenches have vanished long under the plow

          No gas, no barbed wire, no guns firing now.

          But here in this graveyard it's still "No Man's Land",

          The countless white crosses in mute witness stand,

          To man's blind indifference to his fellow man,

          And a whole generation that were butchered and damned.


          Chorus

          And I can't help but wonder, oh Willie McBride

          Do all those who lie here know why they die,

          Did you really believe them when they told you the cause

          Did they really believe that this war would end wars.

          Well, the suffering, the sorrow, the glory, the shame

          The killing and dying it was all done in vain,

          Oh Willie McBride it all happened again,

          And again, and again, and again, and again.
