Spike Jones, not the director, was a bandleader starting in the 40’s who would use anything he could imagine as a percussion instrument, from gunshots to beating on garbage cans. The list of those he influenced goes on and on. Although very silly, i.e. fun, his music is not for the uptight, but should appeal to the clichéd kid in all of us. Though this song doesn’t display the weird instrumentation Spike Jones was known for, except for the “necking” sound effect, it is very silly. I doubt the “eyes” Dracula has for Vampira are the ones in his head.
The singers taking the roles of Dracula and Vampira were famous outside of the band. Paul Frees, “The Man of a Thousand Voices,” was Boris Badenov on The Rocky and Bullwinkle Show and Loulie Jean Norman did the vocalization on the original Star Trek theme, was the ghost opera singer from the Disney Haunted Mansion ride, and was the singing voice of Clara in the movie version of Porgy and Bess.
