Well, I must admit I was fair-what-gobsmacked to find out that it's as English as (erm) Irish-themed pubs. On which subject: about a dozen years ago I went a few times (when there was no decent paint drying to watch at home) to an Irish pub in ~ where else? ~ the depths of post-industrial Lancashire. That pub was called The Craic i' th'Wall, which always sounded to me like a mishmash of pure Irish (Gaelic) and Lanky Twang. It had all the atmosphere of a wake, only without the free-flowing booze, music, noise, brawling, etc. It didn't last.
