I'm surprised anyone bothers to get married at all in Sweden. Do they have Irish people?
………………
Hmmm, well there is the Svensk Irländska Föreningen in Stockholm and a Gaelic football club.
Demonstrations of Irish dancing are available.
That seems to account for most Irish personnel with their significant others (although they're probably the same people) and there's a plug out:
Nu är det dags att anmäla sig till höstens kurser i irländsk dans
Now it's time to sign up for this autumn's Irish dance courses
I wonder if there's a crossover Romish/Church-of-Sweden ceremony available for any who do get married?
