Yeah?! Well then, let me tell ya here "kid" , this series did not "predate" ME!
In fact, I was 6-7 years old when I'd watch it first-run on the then third rated ABC television network. And even at that tender age, I remember memorizing the lyrics to its opening theme song here and would sing along to it as I sat on the floor in front of that old Philco 21in console black & white TV set and prepare to watch each exciting new episode of this early Spanish California masked avenger...
(...and so I guess what I'm sayin' here is, GEE THANKS for makin' me feel old here!)
LOL
