During the party I took over the lead of songs queue, and I've played some brazilian classics such as "A Namorada" by Carlinhos Brown, well known for carnival compositions.
If you wanna see polish people dancing that song in such a funny and crazy way, go ahead:
On the second day, we had an unforgettable 'unofficial' christmas eve, with a tasty banquet. The room was totally decorated for the ocasion.
We also had a Santa Claus and presents. During the presents' delivery, Santa asked me to sing some song in portuguese in order to give me my present. Damn, I was so shy! If I knew I had to perform some stunt I'd probably have gotten drunk before. LOL.
Anyway, I ended up singing "Sozinho" by Peninha. When I was singing I heard nothing else, except for my voice, everybody was staring at my (poor) performance. Damn! my voice is too low! But anyway, for them, it didn't make any difference. They were impressed to hear something in a very beautiful language such as the brazilian portuguese. I even got applauses for that. :P
