Lancelot Link, Secret Chimp is an early 1970s comedy series featuring a cast of chimpanzee spies. It was produced by Sandler-Burns-Marmer and first aired on ABC on September 12, 1970. From Fabulous Sebastian’s review for DVD Purgatory:
Children’s television in the sixties and early seventies was bizarre. Really bizarre. I don’t know if drugs were involved, but reflecting on shows like Batman, The Magic Roundabout, Banana Splits, HR Pufnstuff, and even Sesame Street, makes me think they were. And in large quantities. Perhaps the oddest of them all was Lancelot Link, Secret Chimp, which was produced from 1970 to 1972. Mike Marmer and Stan Burns, probably inspired by the success of Get Smart (where they were writers), Planet of the Apes, and Mr Ed, had the idea to create a spy series using talking chimpanzees. The cost of creating costumes and sets in perfect scale for the apes made it the most expensive Saturday morning children’s show of its time. And it looks fantastic for the effort.
The show centred around Link and his love interest, the glamorous Mata Hairi, who were spies for APE (Agency to Prevent Evil). APE were in a continual war with CHUMP (Criminal Headquarters for Underworld Master Plan), headed by Baron von Butcher (voiced by Bernie Kopell who played Siegfried in Get Smart). Each show also included Lance and friends performing as The Evolution Revolution, who were the coolest band of the time (much cooler than Josie and the Pussycats or The Monkees).
