By 1875 there were over three hundred music halls in London alone, with hundreds more scattered across the British Isles. Frequently named The Empire or The Hippodrome, they became favorite hangouts for people of every class and persuasion. In time, all music hall performances followed a basic format.

Considering that in the latter 19th early 20th centuries, all of Ireland was still a part of the British empire, and considering the banjo was likely introduced to Ireland in the wake of mid 19th century tour of England and Ireland by the American Irish minstrel group the Virginia Minstrels, I'd say there likely was something closely resembling the Victorian and American music hall traditions in Ireland in that era. However, very little research on the music hall/vaudeville/minstrel traditions have been done in Ireland. There wouldn't be very many musicians involved in traditional music in Ireland who would be knowledgeable about the history of the music hall and minstrel traditions.
