I'm not sure exactly who Wade Denning was, but he did several great Halloween records back in the 1970s. He had an excellent range of voices, and he really appealed to children in those days. According to IMDb he was also a jingle maker (he created the Maxwell House jingle) and some compositions for long forgotten TV shows.
Interestingly, he turns up again on Rob Zombie's Halloween (2007) soundtrack. Perhaps, Rob, like a lot of us 70s kids got one of Wade's horror LPs from JC Penny and was glued to the miniature turntable for weeks on end, memorizing its every word.
Monster Mash Sounds of Terror! (1974) has some awesome sounding titles: "Curse of the Zombies", "Buried Alive", "Frankenstein Returns" and "Death Struggle of the Prehistoric Monsters." What child could resist? The Exorcism track is a bit extreme for young'uns I think - it sounds too much like the real deal. Disturbing.
You can download the entire album, or just listen to this track, "The Nightmare of Lost Souls".
