TV is currently broadcasting the funeral ceremony of the Chaplain of the NY Fire Department, Father Mychal Judge, OFM (Order of the Friars of Mary {Francisans}) at St. Francis Assisi Church in NYC.
Father Judge died of heart attack when debris fell on him as he was giving Last Rites to firefighters and police at WTC collapse. The massed pipe bands of Fire and Police departments played "The Minstrel Boy" as the casket was carried in.
Here are the words as I remember them from years of singing them.

"The Minstrel Boy"

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, they 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"
