Correction: Josie and the Pussy Cats clearly predates the Acro Cats as the first cat band in the United States.

Also, if I’m not mistaken, Scooby Do season 2, episode 7 features the mystery van in a heart pounding, high speed chase with the Acro Cats van. I don’t want to give away the ending, but those Acro Cats are unmasked eventually!
