YouTube has several versions that are okay, but none that were excellent. I had not heard of Danny Quinn, but I like his energy on this. It is very much in the style I sang and played thirty and forty years ago. Unfortunately, there's some shtick and another song on this video. Just stop it at 2.00 - you'll thank me.
The Minstrel Boy to the war is gone
In the ranks of death you will find him;
His father's sword he hath girded on,
And his wild harp slung behind him;
"Land of Song!" said the warrior bard,
"Tho' all the world betrays thee,
One sword, at least, thy rights shall guard,
One faithful harp shall praise thee!"
The Minstrel fell! But the foeman's chain
Could not bring that 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 brav'ry!
Thy songs were made for the pure and free,
They shall never sound in slavery!"
Thomas Moore, early 19th
