Gamerstable, which I'm a minor part of, and two of our most recent episodes. None of this is Greyhawk by any stretch but I'm confident you'll enjoy the subject matter. We played a vibrant story called Tower of the Ape, set in the Hyborian age of Conan using the Savage Worlds game system. The Gamerstable guys went all out on the special effects and background music for this fully licensed actual play, the likes of which you won't find anywhere else!
Here is the first two episodes of the Tower of the Ape:
Episode 1: Shadows of Sultanapur
Episode 2: Kozaks and The Kah'mar
