Great story. The studios on Parliament Street were actually in the heart of Cabbagetown, which was a few blocks from the mothership on Jarvis. The neighbourhood had a lot of colourful characters in its day. As a young Rye High student, I occasionally went in there to see tapings of the Royal Canadian Air Farce, which was recorded there for many years.
The story brings to mind what happened to Guy Goma, a computer technician who was at the BBC in London for a job interview and got mistakenly dragged to the newsroom and put on the air for an interview of a much different sort.
