WFMU on it, as always.
5 years ago, DJ Kliph Nesteroff prepared a whole show that revealed the masters from the 1960s television program. Listen in. You might learn something while your ears have a blast. There’s plenty that you might miss if you just listen, so feel free to check out the WFMU blog for more information.
Be warned, many of the links don’t work. Alas, that is the way of the internet. To alleviate your search, here’s a link to the audio.
On a related note, Darryl Cunningham, author of Psychiatric tales, has some art you might like.
A particular highlight: The Hellraisers by Syd Dale
