Of course not! Bien sûr que non! I’ve found other songs (few of them, in fact) but have been hard to find their videoclip or their download links to post here, then I decided keep searching and update them later.
Between them there are: Henri Salvador, who made a song in which there are people whistling the River Kwai March called “Colonel Bogey” but there’s nothing on internet about it for download. And there is a good song by a rap group but in its live show the rappers don’t whistle, they mumble; I'm not sure about post now this kind of “half-whistled” songs in which the whistling isn’t a primacy.
Well, if you don’t mind, into tomorrow update there is a phrase sung in french. Ok?
À bientôt! Et vive la France!
