So, I am literally struggling to find this song. It is quite known: you can hear a choir (like childish) singing in an high key and there is an atmosphere of mystery and secrets. I guess it is quite related to Christmas (no, it is not Carol of the Bells but that is the mood) At least they (tv adverts) often kinda use it during xmas time. I am not that sure but I might have heard it on a car/perfume/climate (saving planet) commercial too...or something like that. Here is the melody: I know you heard it...once in your life at least. Please help me
