There is substantial discussion of the songs of Rody/Roddy McCorley/MacCorley elsewhere in Mudcat. It exposes many of the 'facts' of the matter and certainly bears comparison with Guy Beiner's account and interpretation. However, so far as I know, Guy Beiner is Irish, though employed at an Israeli University. His degrees were from Irish Universities, Much of his research has been into accounts of the 1798 rising in Ireland, so he is well equipped to consider the question of William Archer and his 'gang'. There has been at least on other paper that looked into the post-1798 unrest in Co. Antrim. I can post details if there is interest. There is a very long version of 'You tender hearted Christians' in the National Folklore Archive at University College Dublin.
