Celine Dion has a Christmas song in Fench titled "Les Cloches Du Hameau." If my French is correct (probably NOT, lol) that means "Bells of the Hamlet" or something like that.
In one line, I could swear that she's singing "Les cloches du hameau...ayyamak sa'ieeda...." Well, "Ayyamak sa'ieeda is ARABIC for "May your day be happy", and last time I checked Celine Dion didn't speak any Arabic, so I doubt that's what she's saying.
