One of my favorite records growing up was a Power Records/Peter Pan Records LP called, according to the front cover, A Story of Dracula, the Wolfman, and Frankenstein. (On the LP itself the title is listed as A Story of Dracula, Frankenstein, and the Wolfman, while inside the back cover of the LP book it's called A Story of Dracula Werewolf Frankenstein.) Regardless of the proper title, it's a pretty good listen. Basically the story attempts to bring together all the heavy hitters of horror history by interweaving tales about Dracula, Frankenstein's monster, and a werewolf.
Like most kids' records, there aren't any credits for the actors or musicians. Which is sad because I'd like to know who does the voice of Torc.
I thought it might be an enjoyable Halloween listen for you, so download it and give it a spin (15MB Zip file). We actually have this at WXYC, but I digitized this from the copy I listened to as a wee lad.
The illustrations from the book are included as well. Turn the page when you hear the beep!
