No sorry, Dave is right.
Jorma tells the story that he was driving in his roadster (I assume the same vehicle as on the cover of Burgers) and passed a dojo in S.F. where Hart was taking martial art classes. He saw Hart make a move and imagined the sound it made was "quah." "Hey," Jorma says, "wadda ya want, it was the early 70s."
Take care, - Mark
