One More Week

Since last century until now this is  the 1st song which come to my mind when is Christmas time...
I can say this is not a Christmas song but funny things is X'mas time people like to play this song.
I don't why and I just love to humming  this song. not the "Santa Clause coming to town" but is the " Last Christmas, I gave you my heart"
I can't believe this song I had sang for 26 years already yet this song is still popular in every end of the year.
Merry Christmas and Happy New Year to you all!!!
