I found this write up on the web that unfortunately did have an author attached to it.  If someone knows who wrote this little piece, please let me know.  In any case, it's a nice little writeup on a show that has no information available on it.

The Haunting Hour is a very mysterious show. First, let's note that the Haunting Half-Hour would actually be correct, but an odd title for the show. So Haunting Hour it was.

The second mystery is that, like so many of the great radio talents who labored in the background, unseen and unheralded, this show made for transcription has receded into the ethers of old time radio without a history. That is, the Magister Ludi of Old Time Radio himself, John Dunning, succinctly states in "On the Air, The Encyclopedia of Old Time Radio," "There were no credits, so casts and production crews are unknown."

Vanished without a trace? Were they really there, making real radio? The answer is yes, and the following set of shows proves it. Perhaps you, the kind listeners, might give us a clue to the talents involved. Or were we all just imagining it? It sounds like a plot for another Haunting Hour.

The shows are classic chills from the old school, with creepy organ, overwrought women and over the top men. Perhaps not the highest of melodrama, but obsessively workmanlike. After all, they might have known they were a skeleton staff toiling relentlessly without a ghost of a chance of fame. Thanks to transcription, these unknowns are still with us.
