Samurai Pizza Cats debuted in Japan in 1990, producing 54 episodes over the course of one year. The series was imported to the US by Haim Saban, who at the time was best known as a theme music composer (i.e. Inspector Gadget) with writing partner Shuki Levy. Remember, this was a couple of years before Saban became a major player in American television when he acquired the rights to the Mighty Morphin Power Rangers.
As my memory serves, however, the Pizza Cats resurfaced a few years later for a 2nd go-round, right around the time another Saban entry, Eagle Riders, based on Japan's popular Gatchaman franchise (better known here in the US as Battle of the Planets). I may be wrong, of course.
Series writer Michael Airington, doing a mimic of actor Paul Lynde, recorded the theme for the American version of Pizza Cats, uploaded by Airhammer to YouTube:
Now, I never saw the show, so I can't give a fair rating. It amazes me, however, that the series has not been given another chance, even on the Anime Network (which only has an On Demand berth on Time Warner Cable to date).
