What makes this song particularly bad is that it is performed by someone who was - supposedly, can't see it meself - a great singer: Peggy Lee; and by a - genuinely, truly - great songwriter: Irving Berlin.
I can only presume that this one was salvaged from his reject bin, pieced together, and issued while he was held at gunpoint.
Then again, there's no particular reason why we should expect a lapsed Jew to produce a genuinely good Christmas song. Becoming ridiculously popular for his subversive duds rather than his romantic marvels is hardly Berlin's fault!
Indeed, Berlin was, of course, responsible for White Christmas which was, allegedly, the most frequently-sung song in the world after Happy Birthday To You (from which much can be inferred concerning the human race); about which the only positive thing that can be said, is that it is considerably better than Happy Holiday.

The calendar system just is based on the (assumed) birth of Christ, but renaming it to pretend it isn't is exactly the kind of deniable, passive-aggressive, girly-slap-fight wimpishness that we can reliably expect from politically correct academics.
Note: Let's remind ourselves that Berlin could write a lovely song, performed here by the late and (by me) lamented Peter Skellern:
