This is a beautiful Christmas song by Belgian singer Will Tura. The title translates to "Christmas song" and it is featured on Tura's 1978 album "Vrolijk Kerstfeest, gelukkig Nieuwjaar" (which translates to "Merry Christmas, happy new year"). My parents used to have the cassette version of this album which they played in the car back when I was a child. Later, they gave that cassette to me and in about 1993, I did my own version with the one-man-band.
