Capt. 20 still has a pretty big following in the DC area and beyond. I ran into him at a science fiction con in DC in the late 70s/early 80s, recognized him, and he hushed me so that he wasn’t recognized. 
As it is, I mention him (though not by name) in the intro to my book. I should find his email address and let him know that! Those movies in no small part made me what I am today: a major slacker.
