It very much seems and looks like you are struggling with my Trivia. So rather than address the questions and admit you are defeated, you have turned your attention to the quizmaster. You are trying to trip me up, trying to personally ridicule me, even tho you don't know me, or know anything about me. What is your problem? if you don't have the knowledge to answer the Trivia questions, then leave it to others to solve. Because you seem like a very bitter, sarcastic little man, as your above posts imply.
The WHOLE of Ireland was part of the UK until 1922. Doyle was born in 1913. So you've kind of proved yourself wrong there.
Barry McGuigan was born in Republic of Ireland though. But he didn't sing. His father did the singing. Jack Doyle born in United Kingdom of Great Britain and Ireland. And he did sing!
