Dịch - Portuguese-Swedish - Parabéns a vôce nesta data querida!muitas...

The words are something like:

"Gratulerar på dig i den kär dag, mycket lycka, många år av liv. Idag är högtidsstund, vår själar sjunger! på flicka C. handklappning!"

This is the song we often sing when someone has birthday.
meaning:
May you live!
May you live for a hundred years
Of course you shall live!
Of course you shall live for a hundred years!

Four times Hurra for C.. Hurra....

Is the portugese text the equivalent song?

Exactly! I should have written that in the remarks.

"fyraldigt" --> "fyrfaldigt"

Hi Lilian!
I think you can shorten it a bit. The two first lines in each vers is enough. We usually sing it with only four lines.

Done! Is that right?
