Oh my god, I am so sorry to forgot to tell you that I don't speak french at that time. That's why I said it sounds like, but not the same words. To pin point it, it is:

1- from the 1983-85.
2- I heard it on RMC (Radio Monte Carlo) The top ten Hits program.
3- It is a disco rythem.
4- The first to the third line, with the third line has the extended pas or va, and they (SOUND LIKE in French).

'Oh, ?oui ?tou ma ?lou ma ?lou ?rit (va or pas).
....?...?J'amie ?n'arit (va or pas).
....?...?......(va or pas)aaah..aaah..aaah..aaah..aaah.


5- I don't know where to find the top French hits of the 1980-90 where I could remember the name of the group or the song.
