* This title was the subject of a later suit, also successfully defended. The title technically does not claim they cure cancer, only that they are heroes of it.
Hoppin', Boppin' & Never Stoppin' : How Jazzercise Can Instantly Cure Your Cancer and Make You Live Forever - Seriously! is an instructional Jazzercize VHS series that notably led to the death of Jeb Stoves, decades after the title's claim was exposed as fraudulent at best. The series had a subscription model, releasing a new VHS every month from October, 1985 to January, 1991.
Concept
The series features live music sets by smooth jazz multi-instrumentalist duo Hopson "Hop" Benson & Doctor LaRoy Bopp of Hop-n-Bopp, which are accompanied by the musical aerobic instruction of personal trainer Jørgen "Never Stop (Doing Jazzercise Regularly)" Bundgaard.
The jazzercise portions are occasionally interspersed with commentary by the three, most frequently Bundgaard. The comments were anything from encouraging phrases to schizoid religious ramblings, to tidbits of health and wellness advice.
Legal Troubles
Hop-Bop-Never Stop, PA, the legal entity formed by the trio to produce and distribute the product, was the target of massive class-action lawsuits that claimed the series promised to cure their cancer. The plaintiffs were thousands of viewers of the series who forewent medical treatment of their cancers in lieu of jazzercise. The suit was spearheaded by the California Cancer Legal Advocacy Association (CCLAA).
Proceedings hit especial troubles due to the fact that the entity is a Professional Association that contains no actual professionals. Doctor LaRoy Bopp was convicted of contempt of court for frequent outbursts that he held doctoral qualifications in various fields to include Boogie, Boppin', Gynecology and Boogie-Boppin'.
However, the civil and criminal charges were dismissed based on a single clip from Vol. IV, Tape 12 - A Christmas Boogie To Have Your Family Watch While You Do, in which Bundgaard says, "Here's the Answer: It Doesn't!" The clip was presented as the answer to the prospect of a cancer cure presented in the series title ("How Jazzercise can instantly cure your cancer and make you live forever"). The veracity of this claim was deeply questioned, but even the original recording of the program is so badly distorted by multiple transitions from 8mm film to BetaMax to VHS that it is impossible to tell.
Additionally, the defendants were awarded reparations in a countersuit, a landmark class-defendant action that bankrupted the families of thousands of cancer victims. The CCLAA was ordered to declare all three of the plaintiffs "Heroes of Curing Cancer*" and to fund massive marble statues of them on its campus. It declared bankruptcy soon after.
