If you have not heard it yet, Ken appeared on the podcast Radio Rashy. Here is the episode description:
The merriment continues with special guest Kenneth Plume, of www.asitecalledfred.com. Ken's world-famous impersonation of Brian Blessed caps a show dealing with Misty's plans to steal pudu, the tale of Paul's aborted Dastardly & Muttley movie and how inflatable Donald Duck swim rings might have saved lives aboard the Titanic. All this, plus Emily's new tie!
