There's a Christian version of You Tube - it's called God Tube (http://www.godtube.com/).
There's a variety of groups and videos on there - some great music videos, talks, skits, and so one. There's also some Catholic ones.
And when I searched there for Chesterton, I found a Gilbert monologue.
Check it out.
If I knew how to link a video, I would. http://www.godtube.com/view_video.php?viewkey=dc2a6340e258630febd5 This is the best I can do!
UPDATE: Here it is, "embedded":
"Let us begin the League of the Free Families!"
