Count John McCormack has a tenuous link with my family. His father and my great-grandfather were at odds over their competition for the foreman's job at their factory in Athlone. The story goes that fisticuffs were even resorted to, and that his father came out victorious (at least when it came to getting the job, dunno about the fist-fight). I have some wonderful versions of Irish ballads sung by him in his later years, when his voice had allegedly lost some of its youthful flexibility. I have to confess that I have no idea what you're talking about in describing his delivery as in any way "nasal". That's the last thing I'd have said about his singing.
