Happy birthday, neoblaze - a day late.
Here's a Polish tradition for birthdays. They don't really sing "Happy Birthday" to anyone because they really don't celebrate birthdays as much as they do name days. (I'm talking those that are in Poland, after a generation or 2 here those traditions go out the window - modern life.)
So here goes in Polish first then the translation
Sto lat, Sto lat,
niech zyje zyje nam.
Sto lat, sto lat,
niech zyje zyje nam.
Jeszcze raz, jeszcze raz, niech zyje zyje nam.
Niech zyje nam!
100 years, 100 years
May you live 100 years
100 years, 100 years
May you live 100 years
Once again, once again, may you live 100 years.
May you live 100 years!
Happy birthday. I hope it was the best.
