I think the Bard of Armagh was the one I was trying to remember. I am not familiar with St. James Infirmary as the same tune as Pills of White Mercury, the version of St. James Infirmary that I know, is a more blusey piece. The group Old Blind Dogs does a version of the Barnyards of Delgaty which also isn't listed on the DT, only refered to in the Song on Courtship. They also do a fiddle piece called Two Pretty Maids that is absolute "chicken skin" music and a number of other songs, the lyrics of which I don't think are listed.
