Question: There was a show on Saturday mornings in the mid-'70s that no one my age seems to remember. I bow to your archival brain and resources. It was a Sid and Marty Krofft-type show, in a variety format, emceed by a goofy band called Kaptain Kool and the Kongs (who were they really?). They had segments such as "The Island of Doctor Shrinker" with Billy Barty as Dr. Shrinker's assistant and "Electra Woman." Reagan
Televisionary: It was more than Krofft-like, Reagan. It was an actual Krofft production and as regular readers know well, I never tire of writing about all things Krofft since, being a child of the '70s, I was weaned on that stuff.
You're talking about The Krofft Supershow, which ran on ABC's Saturday-morning schedule for two years beginning in September 1976. Hosted by rock band Kaptain Kool and the Kongs (whose members were the good Kaptain, Superchick, Turkey, Nashville and Flatbush), the series consisted of short segments such as those you mentioned Dr. Shrinker and Electra Woman and Dyna Girl plus, over the course of its run, a varying schedule that included Wonderbug, The Lost Saucer, Magic Mongo and Bigfoot and Wildboy (for more on that last one, click here.)
As for who the Kongs actually were, Michael Lembeck (One Day at a Time) was Kaptain Kool, Debra Clinger (The American Girls) was Superchick, Mickey McMeel was Turkey, Louise Duart (DC Follies) was Nashville and Bert Sommer was Flatbush for one season, before the character disappeared.
It's worth noting, by the way, that while Kaptain Kool and the Kongs went on to show up on other Krofft shows (Donny and Marie among them), they were gone when the series made the jump to NBC in 1978. The Bay City Rollers took over as hosts, but not for long. The show was canned after a few months.
