About 900 people — mostly an older crowd — filled the hall, with no pre-speech protests or demonstrations.
As the lads from ARC point out:
Keep in mind that, after what we believe was a contrived controversy to drum up more publicity, the organizers believed that there would be 1000 tickets sold and that the balconies might also be filled.
Although to be fair, the LFP article says that the speech was at London's Centennial Hall, which means it was moved from the University of Western Ontario at what must have been the last minute. Which might have confused Mark's elderly fans.
