Released at the height of the psychedelic era, with allusions to all things far out and groovy. Even Pinky's lamp and chair have a late 60's design.
Censorship was a hot topic at the time, with free speech, nudity in films and theater, and more, being in the spotlight. Even Rowan and Martin's Laugh In devoted a musical number to the controversy.
The music here has a late 60's beat to it, with bongo drums and sci fi sound effects adding to the effect.
One of the few times Pinky smokes during the actual short, rather than only in the opening credits.
