Canon Wired has a set of videos including lectures delivered by Doug Wilson on a university campus. There are some minor points I would probably disagree with Wilson on, but it was nice to see that he gave a clear, evangelistic message as part of the presentation.
I thought I had previously posted a clip that showed one of the disruptions that took place during this presentation, though perhaps I did I not. Wilson does a good job of keeping fairly calm throughout the heckling and "protesting."
I found it interesting to listen to the 2 hr. Q&A session first, and then go back and listen to the lectures (about 1 hr. 15 min. combined). It helped to highlight points where what the students heard was not necessarily what was said. It was also interesting to see how some of the people from the Q&A behaved during the lecture.
