On 23. March 1974, Gene Simmons did his blood spitting routine live for the first time when playing a Kiss show at The Academy Of Music, New York.

Gene Simmons:
“I remember seeing Christopher Lee as Dracula in one of the Hammer films, Blood of Dracula or Horror of Dracula. I’ll never forget when he bit into something and his mouth was covered with blood. I thought, that’s cool, I should do that onstage. Why? Why do little boys stick frogs up girls’ skirts? Because they squeal and that’s fun.”
– “Kiss: Behind the mask”, p153
