From a USA Today story about the decline of Christmas caroling, here’s a tasty nugget of holiday cheer:

Yet, caroling is ancient (the first Christmas carol was probably written in the 4th century, Studwell says), and associated with pre-Christian festivals, fertility rites, feasting and drinking — the antique equivalents of sex, drugs and rock ‘n’ roll. In medieval Europe, caroling referred to singing that accompanied dancing and merrymaking.

“Before 1800, it was public, rowdy, drunken, potentially violent, often sexual, and of course now we have New Year’s Eve for all that,” says Stephen Nissenbaum, professor emeritus at the University of Massachusetts and author of The Battle for Christmas.

He says wassailing (from the Anglo-Saxon was hail, or good health — a kind of medieval version of whassup) was a form of caroling that amounted to “aggressive begging.” Poor people would go to homes of the rich and sing, and if no one coughed up cash or treat, they could expect a trick .

I propose a new slogan for Christmas traditionalists: Debauchery is the reason for the season.
