It's fun to sing eurovision songs in foreign languages! Especially the ones you can barely, or not at all understand.

I've been doing quite good with my French (I did study it for a while after all)...
Allez Allez Allez Allez Allez, Il faut danser
Tout le monde, danser, tout le monde, danser collé serré!

...surprisingly good with my Serbian (I think I'm a natural)...
Ljubiš me k'o balavica, nije te sram
Beograd, Beograd, ja bezobrazan
Ne jednom, ne dvaput, tri puta me
Beograd, Beograd, tri puta po naški je.

...but the Greek is a tough one!
Ola tha t' allakso - OPA!
Kai tha to fonakso - OPA!
Perasmena ksehasmena ki ola ap' tin archi ksana
