If you have a I pad or tablet and can get to I tunes U (Open University) (brown Icon) and once in type the heading in this blog you should get the podcasts to watch. Willard died a few years ago. He is not greatly known in Scotland. I know Pitlochry Baptist Church have used some of his material.
Enjoy the listen and search for more of his stuff. Refreshing, not stuffy, and bear with the Americanisms.
