The song is written from the perspective of a doomed young Wexford rebel who is about to sacrifice his relationship with his loved one and plunge into the cauldron of violence associated with the 1798 rebellion in Ireland. The references to barley in the song derive from the fact that the rebels often carried barley oats in their pockets as provisions for when on the march. This gave rise to the post-rebellion phenomenon of barley growing and marking the "croppy-holes", mass unmarked graves which slain rebels were thrown into, symbolising the regenerative nature of Irish resistance to British rule.
It was featured in the 2006 Irish award winning film The Wind That Shakes the Barley during the scene of a wake. An arragement for SATB choir by Laurie A. Betts was published by Walton Music Publications in 2008.
