What PBS show was this?

I know I’m not crazy and I am certain this show existed.

It was a show that read fairly classic children’s stories and made them into cartoons. I’m not talking about Reading Rainbow.

The set was really simple. I hanging window with a starlit sky. A smoking chair. Those fancy looking wooden ones with the padding and fabric stitched on. And a tall lamp. The set was darkly lit.

Here’s the format of the show as I remember it. They would start on the set. There would be sitting James Earl Jones, or some other heavyset black guy with a big voice. I’m not really sure if it was him or not. He would do an introduction and then the story/cartoon would begin.

I remember they did something like Abel’s Island. There was also this other story that showed king Arthur as a teen where he talked to Merlin about nightmares he had. He was dreaming about these blue and red dragons sleeping under the earth beneath two castles. And as they breathed it would shake them and topple the castles. In the end the dragons did battle.

Another story I vaguely remember had a rooster in it and it was set in winter.

If you have a clue what I’m talking about please tell me.
