this is a really easy way of playing this, it's not correct i know, but sounds fine.
G C G C
The minstrel boy to the war is gone,
G Em D G
In the ranks of death ye will find him;
G C G C
His father's sword he hath girded on,
G Em D G
And his wild harp slung behind him;
Em C D G
"Land of Song!" said the warrior bard,
C Em C D
"Tho' all the world betray thee,
G C G C
One sword, at least, thy rights shall guard,
G Em D G
One faithful harp shall praise thee!"
The Minstrel fell! But the foeman's chain
Could not bring his proud soul under;
The harp he lov'd ne'er spoke again,
For he tore its chords asunder;
And said "No chains shall sully thee,
Thou soul of love and bravery!
Thy songs were made for the pure and free
They shall never sound in slavery!"
