Mark from the Royal Canadian Air Farce reminded me that the public is invited to sit in on tapings of the show. He wrote:

A friend of mine, a non-CBC viewer, recently attended a taping at my urging, and was struck at what a great time he had. With new cast members and a faster pace, Air Farce is not the same show most people tuned out long ago, but is instead a revitalized program, still taking shots at our nation's leaders and other public figures.

At an hour-and-a-half, the taping was not long, and he was surprised at what he called "Toronto's best-kept secret"... that is, a free night out in downtown Toronto, with some great entertainment and a unique behind-the-scenes look at a major weekly television show (still CBC's highest-rated sketch comedy show on its schedule).

There are six weeks left in the season and plently of free tickets to see the shows. More info on the web site.
