There was a short-lived punk rock band in the late 1970s that took their name from this movie (and included former New York Dolls bassist Arthur Kane in their ranks). Their gimmick was wearing ghoulish make-up.
In a 1971 radio ad, they announced to see this film the viewer needed to sign a waiver before you entered the theater, saying you are assured of your mind, sound and body, and the theater or distributor's cannot be liable if a person was horrified so greatly you became ill.
Re-released to theaters as "The Flesh Grinders" in 1980 on double and triple-feature bills, mostly in the Eastern U.S. It ran until 1985 and was often paired with Penitentiary, The Gates of Hell, Bloodeaters, Zombie, Massacre at Central High, The Rats Are Coming The Werewolves Are Here, Night of the Living Dead, Last House on the Left II, Meat Cleaver Massacre, Funeral Home, Nightmare, The Man With Two Heads and others.
