https://tunearch.org/wiki/Crotty%27s_Lament_%281%29 includes a story from John Edward Walsh's book Ireland Sixty Years Ago (1847, republished by M.H. Gill & Son Ltd., 1911) which describes Crotty in mostly unsavoury terms; saying that he was a cannibal and that he engaged in gratuitous acts of cruelty. But at the same time, he was liked because he shared his plunder with the poor.

sheet music is at the bottom of the tune arch page.

I have never found the poem Stól a' Chrotaigh nor any Irish language words for Crotty's Lament. Neither the link to the Carrick People page or the Rathcormack com page works now. I regret not having copied the English language version of the poem about Crotty's Stool.
