Groovie Goolies aired on TV from 1970 to 1972. It was produced by Filmation and was a spin-off of Sabrina the Teenage Witch.

The show featured knock-offs of Universal’s famous monsters except that they were all hip and happening monsters. Every episode they performed a pop song, which seemed to be the standard requirement of most cartoons made in the late ’60s and early ’70s.

The Goolies all resided in Horrible Hall – a boarding house for monsters. The show was modeled after the then popular Laugh-In TV show. A typical episode would feature some random sketches, bad jokes and then a musical number or two. Groovy stuff indeed.
