For me,the greatest ballad on the world,trully. These are the chords I use. The original 
from G#,but I put in on C,much easier to play. Done the first verse and refrain. Other 
are the same as the first one,so it sould be easy to get it. Enjoy (:

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 nineteen
Or are you a stranger without even a name
Forever enshrined behind some old glass pane
In an old photograph torn, tattered, and stained
And faded to yellow in a brown leather frame

Did they beat the drums slowly
Did they play the fife lowly
Did they sound the death march as they lowered you down
Did the band play the last post and chorus
Did the pipes play the flowers of the forest

The sun 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 that's still no mans land
The countless white crosses in mute witness stand
To man's blind indifference to his fellow man
And a whole generation were butchered and damned

Did they beat the drums slowly
Did they play the fife lowly
Did they sound the death march as they lowered you down
Did the band play the last post and chorus
Did the pipes play the flowers of the forest

And I can't help but wonder oh Willy McBride
Do all those who lie here know why they died
Did you really believe them when they told you the cause
Did you 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 Willy McBride it all happened again
And again, and again, and again, and again

Did they beat the drums slowly
Did they play the fife lowly
Did they sound the death march as they lowered you down
Did the band play the last post and chorus
Did the pipes play the flowers of the forest
