The Mancini original is by far the best. (my opinion). First heard it in the early 70s in Chicago on WGN channel 9, “Creature Feature” 10:30 PM Saturday night—unforgettable! Al Caiola’s version (used for “Chiller Theater”) is pretty good, more playful—-but Mancini’s is pure genius—the harp flourishes, the lush strings in the epic bridge section—& that sinister 6/8; perfection!
