So that's what he sounded like!
Thanks to Hallowed Ground for linking to this amazing clip from YouTube which has sound recordings of GK Chesterton - apparently the only ones that exist. When I visited Toronto many years ago, the parish priest told me to speak slowly when preaching because the people found my "accent" difficult to understand. I suppose this is why the text is posted in sync with Chesterton's words in this clip. He is very complimentary about Canadians, by the way.
