It's not just Mrs. Nesmith

We all know that the Monkees' Mike Nesmith's mother invented liquid paper. But how many of these other rock-n'-roll family inventions are you familiar with... 

 

Elton John's parents are jointly responsible for the "pop-up house". These paper homes, while certifiably stable (see photo above) were never mass-produced owing to the prohibitively large number of children needed to get one open.

 

 

 

David Crosby's father Werner invented "gree-ellow" - a colour David refused to ever sport.  

 

 

 

Jefferson Airplane's Grace Slick's mother invented the "baby".

 

 

Donovan shows off just three of the identity-changing cosmetic treatments pioneered by his dog "Doctor McAllistair".   

 

 

Richie Havens models the nuclear coolant synthesised by his conjoined siblings Sweets and Gummo.

 

 

Uncle Gretchen poses with the patented Succubus-Absorbent Silverware he used to exorcise a grateful Eric Clapton.

 

 

 

And of course Frank Zappa's sofa invented holograms.
