If, the day after your birthday, you visit friends in Poland, you shouldn’t be surprised to get a spontaneous rendition of “Sto Lat”

Sto lat, sto lat,
Niech żyje, żyje nam.
Sto lat, sto lat,
Niech żyje, żyje nam,
Jeszcze raz, jeszcze raz, niech żyje, żyje nam,
Niech żyje nam!

If the friends are deeply rooted in the Polish Highlander tradition, you shouldn’t be surprised when Pan Gospodarz dashes off beforehand and returns with his altówka (viola) to accompany the marry well-wishers.

And with that many instruments, it could hardly come as a surprise that all the kids decide to form a band.
