I think it's great btw. I'm very much in the 'celebrate everything' camp. Tokyo can't have a significant Irish population though?

But at that time Strathclyde, Cumbria etc were Welsh.

Ireland has been extremely well marketed

It's a great excuse for a piss up.

It definitely is and us Irish love a party 🇮🇪🥳
