Pauline, follow this link to Archie Fisher's Travelling Folk Show.
As I mentioned, each two-hour show is available for an entire week by clicking the "Listen Again" button. He plays a wonderful variety of folk, leaning heavily on traditional material, and including both the U.K. and North America. Enjoy!
BBC Scotland Travelling Folk with Archie Fisher

Lester Simpson's show on BBC Derby is linked on my computer at work, so I'll add it to this thread tomorrow.
