Well Mrs. Duck,

That has its origins in the founding of the USA and the disdain for official state religions, as was then common in Europe. However, IMHO, our constitional prohibition against the establishment of a religion was never intended to be used as a sword to prohibit public displays of any religion. Yet that is what it has become.

Anyway, back to the thread. Mine has to be White Christmas, only becasue every time I hear that song, I can still he my Dad going through the house whistling the tune as we put up the decorations and things. I still play it when decorating my house each year.
