A Vegan's Boar's Head Carol?

The San Francisco Bach Choir combined fun and beauty in a  wonderful way last Friday  at a Candlelight Service at Calvary Presbyterian Church, but I was a little confused about part of the fun.

Is this a chocolate boar's head?

Here are the words to one of the songs they sang in the category of The Community Celebrates.

The boar's head  in hand bear I,

bedecked with bays and rosemary.

and I pray you, my masters, be merry,

Quot estis in convivio [As many as are in the feast].

Capput apri  defero [I bring in the boar's head]

Reddens laudes Domino [Giving thanks to the Lord].

The cheese plate aloft I bring.That vegetarians may sing.

Though you eschew the flesh of pork

Still raise a glass and wield your fork!

Caput cheese plate...[I bring the cheese plate].

The boar's head as I understand,

is the rarest dish in all the land,

which thus bedecked with a gay garland

let us servire cantico [Let us serve with a song].

Caput apri...[I bring in the boar's head]

Fie then, sirs, and shame on you!

Abhor the boar, and serve tofu

This gorgeous block of gleaming white,

hic bean-um bonum servio!

Caput tofu...[I bring in the tofo].

Our steward hath provided this

in honor of the Queen of Bliss,

which on this day shall be served is (us?)

in reginesi atrio [In the hall of Queen's College].

Caput apri...[I bring in the boar's head].

Advice for the modern host:

You need not kill the thing you roast.

In faith whereof I propose this toast:

Ally ally al-ly oxen free!

Caput vino...[I bring in the wine].

Our cook hath roasted brussels sprouts,

and beans with garlic fill the house

a meal for friends of pigs and cows

in verdurum vivero

Caput garlic...[I bring in the garlic]

I would think this were funnier if I didn't fear that this really is the image people have of vegetarians--and they're not even talking of vegans!  To be continued!
