For those still mourning the old Harvard Square — the funky one alive with buskers and late-night rowdiness at The Tasty, the one before Abercrombie & Fitch and all the bank branches — the announcement of the Harvard Square Business Association’s 100th anniversary gala will seem a bitter epilogue.

Tickets to the Nov. 20 event are $250. The square has always had a component for the wealthy, of course. And if you’re into that kind of thing, the association’s description makes the gala sound pretty swell:

After a 5:30 p.m. tree lighting in Winthrop Park, there will be simultaneous hourlong cocktail receptions, one with a keynote speaker for major sponsors; a station-style dinner with reserved seats; a 9 p.m. official program with a short-film premiere and awards; and dessert at 9:50 p.m. and dancing until midnight when, says Executive Director Denise Jillson, those present will “ring in the new millennium.”

(This is fair. Even though the association was formed in 1910, anyone can ring in a next thousand years at any time. Time is arbitrary in this way.)

It will be “a fabulous and memorable party,” she said.

There will also be a cigar tent.
