Allan Sherman was a comedian, successful in the 50s and 60s, who invented game shows, wrote and produced for television, sang novelty songs, and guest-hosted The Tonight Show. He was most famous for the summer camp song “Hello Muddah, Hello Faddah.” He had several comedy albums like My Son, The Nut and My Son, The Folk Singer.
My Son, The Vampire was a movie from 1951, starring Bela Lugosi and, unlike the earlier posted White Zombie, is not very good at all. The movie was re-released in 1963 with Allan Sherman’s song added to the titles. In the song, “Blood” is pronounced so strangely to mock the way Bela said the word.
