Just a demo. I don't remember whether it was in Tom Bleecker's book or his '78 Black Belt magazine yearbook article, but he wrote about introducing Bruce to O'Neal & Bruce demonstrating both his speed & power on an initially doubtful O'Neal. O'Neal was holding a kicking shield or some other kind of pad when Bruce kicked him into a trailer. Dan Inosanto also mentioned this incident in one of his books, saying he'd heard it from a "very reliable source" (Bleecker?).
