I want to know the answer to the following question:
Which major opera singers were born in Cork?
All the background I'm provided with is that "Ranging in capacity from 50 to 1,000, the main music venues in the city are the Cork Opera House (capacity c.1000), Cyprus Avenue, Triskel Christchurch, the Roundy, the Savoy and Coughlan's.[citation needed]". Is that enough to answer the question?
