Second half of my post disappeared. Don't know why.

Deck the bars with Christmas drinking
Fa-la-la-la-la la-la-la-la
See the people getting stinking
Fa-la-la-la-la la-la-la-la
Though their brains are half corroded,
Fa-la-la la-la-la la-la-la
Still they try to drive home loaded
Fa-la-la-la-la la-la-la-la.

See the busy intersection
Fa-la-la-la-la la-la-la-la
Here come cars from each from each direction
Fa-la-la-la-la la-la-la-la
See the pile-up as they're meeting
Fa-la-la la-la-la la-la-la
What a novel Christmas greeting
Fa-la-la-la-la la-la-la-la

Do you know, that must have been rattling around in my head for 35 years and - apart from humming it to myself - I've never had any cause to use it, until now. This will probably prove quite cathartic. Thanks, Fred.
