The only featured host that I recognized was Elvira. And of course Vampira, though she retired from the biz probably before I was born. And Elvira was never big in Saint Louis, though I think she ran for a year or two in the 90's. The big one for my youth was Seymour on "Seymour Presents". I don't know his real name, but I remember reading his obit in an issue of Fangoria over 30 years ago. He ran for a few years in the Lou. And they missed him in this doc. Doctor Morgus is alive and well, and shows up on occasion as a guest on "Coast to Coast AM" with George Noory. Check the Coast to Coast web-site, you may be able find audio clips.
