Sure, it was a stupid show. But it had music, some romance, and hijinks. Those were the three requisites for Saturday morning cartoons in the 70s. And in the larger scheme of things, it helped millions of little kids realize that blacks and whites COULD get along. I mean, if The Pussy Cats could do it, why couldn't we kids?
This show actually had a very long shelf-life. It premiered in 1970, and was still on the air in 1976. It had been updated as JOSIE & THE PUSSYCATS in OUTER SPACE, but there was obviously enough fan support to keep it on the air. Those singing women were doing something right!
