I have an LP, 'Easter Week and After', Topic 12T44, where all the songs are sung by Dominic Behan. The last cut on side 2 is his own, "The Patriot Game". The anonymous note on the jacket reads:

Feargal O'Hanlon, aged 17 from Ballybay Co. Monaghan, a draughtsman with Monaghan Co. Council, was killed in action during the Brookeborough Barracks attack also. The song is one of the best and certainly the hardest hitting to come out of Ireland since the Civil War. Words and music are by Dominic Behan.
