Everything on site from this group is in Portuguese (even though they are Belgian), but I'm not sure about this (very odd) one. Can anybody tell?
Most likely Tahitian.

I was the editor who added that work to the database. I really don't think it's Tahitian, coming from Belgian artists who have probably never set foot in Tahiti. BTW, Yves Roche was born in Tahiti. Also, look at all of the adaptations in other languages.
Oh, that's alright. 
Yeah, it's not that good. I'm now guessing it's either Flemish or French. Thanks for helping.
It's not Portuguese, Flemish nor French.
My guess: There are so little lyrics in the Two Man Sound version, they are probably straight from the Haitian traditional.
Bastien, you probably mean Tahitian traditional. That would also be my guess.
