It was...not the world's best show. The characters had simplistic names that told their personality (Courage! IQ! Harmony!) and not only was the villain Martha Raye, but Billy Barty played their firefly pal. It only ran one season, but man, when I see it again, I just crack up. (Watch them sing happy birthday to Joy here!)
Did you ever watch The Bugaloos? They were part of the Krofft empire, of course. Also, the uber-catchy theme song was written by the songwriters who wrote "Killing Me Softly With His Song." Now THAT'S some 1970s musical trivia for ya right there.
Although it only lasted one sad season, you can now buy The Bugaloos on DVD. Were you a fan?
