St Stephan's Day

You've seen this before but it's worth a reprint in honour of the day that's in it.

There are old traditions that even the most traditionalist clergy are highly unlikely to ever want reinstated. Today, St Stephen's Day, used to have one called "stephening" in the parish of Drayton Beauchamp, Bucks. It is probably at the top of that "unwanted" list. From the 1869 edition of Chambers' "Book of Days, A Miscellany of Popular Antiquities in Connection with the Calendar, Including Anecdote, Biography, & History, Curiosities of Literature and Oddities of Human Life and Character":

In the parish of Drayton Beauchamp, Bucks, there existed long an ancient custom, called Stephening, from the day on which it took place. On St. Stephen's Day, all the inhabitants used to pay a visit to the rectory, and practically assert their right to partake of as much bread and cheese and ale as they chose at the rector's expense. On one of these occasions, according to local tradition, the then rector, being a penurious old bachelor, determined to put a stop, if possible, to this rather expensive and unceremonious visit from his parishioners. Accordingly, when St. Stephen's Day arrived, he ordered his housekeeper not to open the window-shutters, or unlock the doors of the house, and to remain perfectly silent and motionless whenever any person was heard approaching. At the usual time the parishioners began to cluster about the house. They knocked first at one door, then at the other, then tried to open them, and on finding them fastened, they called aloud for admittance. No voice replied. No movement was heard within. 'Surely the rector and his house-keeper must both be dead!' exclaimed several voices at once, and a general awe pervaded the whole group. Eyes were then applied to the key-holes, and to every crevice in the window-shutters, when the rector was seen beckoning his old terrified housekeeper to sit still and silent. A simultaneous shout convinced him that his design was under-stood. Still he consoled himself with the hope that his larder and his cellar were secure, as the house could not be entered. But his hope was speedily dissipated. Ladders were reared against the roof, tiles were hastily thrown off, half-a-dozen sturdy young men entered, rushed down the stairs, and threw open both the outer-doors. In a trice, a hundred or more unwelcome visitors rushed into the house, and began unceremoniously to help themselves to such fare as the larder and cellar afforded; for no special stores having been provided for the occasion, there was not half enough bread and cheese for such a multitude. To the rector and his housekeeper, that festival was converted into the most rigid fast-day they had ever observed. 

After this signal triumph, the parishioners of Drayton regularly exercised their 'privilege of Stephening' till the incumbency of the Rev. Basil Wood, who was presented to the living in 1808. Finding that the custom gave rise to much rioting and drunkenness, he discontinued it, and distributed instead an annual sum of money in proportion to the number of claimants. But as the population of the parish greatly increased, and as he did not consider himself bound to continue the practice, he was induced, about the year 1827, to withhold his annual payments; and so the custom became finally abolished. For some years, however, after its discontinuance, the people used to go to the rectory for the accustomed bounty, but were always refused. 

In the year 1834, the commissioners appointed to inquire concerning charities, made an investigation into this custom, and several of the inhabitants of Drayton gave evidence on the occasion, but nothing was elicited to shew its origin or duration, nor was any legal proof advanced showing that the rector was bound to comply with such a demand. Many of the present inhabitants of the parish remember the custom, and some of them have heard their parents say, that it had been observed:
'As long as the sun had shone,
And the waters had run.'

Chambers has even more oddments about St Stephan's Day here.

So . . . I hear you ask . . . what's all that stuff about burying the wren in the song?

Well, in a reprint from a different year, The Inn had this:

The 26th December is known as St Stephen's Day in Ireland. In Northern Ireland it's also known as Boxing Day. In most homes it is a sociable day, when visitors may call in to share some seasonal foods or liquid (usually alcoholic) refreshments. . . . . St Stephens is also the day when a purely Irish phenomenon can be witnessed: the tradition of Hunting the Wren. This is when the Wren Boys take to the streets in colourful costumes and masks, and noisily parade a dead wren on a decorated pole. It's a strange tradition and its origins are often debated. Some say it originated in Pagan times. Others from the Viking invasion. Most opt for a simplified religious reference: the betrayal by a wren of St Stephen who was hiding from the Romans who subsequently killed him for his Christian beliefs. Wren on tree branch This, then, gave the reason for hunting down the wren, and in olden days a bird was, indeed, captured and killed. The Wren Boys would then carry the dead bird on a pole from house to house and beg for money to bury the 'evil bird'. . . .
