One person who knew a lot about Arnold was Ric Drasin & although invited to be interviewed..Arnold always declined... 
Donny, do you think that Arnold’s groomer’s were supplying him with alcohol and drugs? (other than steroids).
Jimmy Savile said something about the first time that he saw Arnold... he said that in the anticipation, it felt as though he could hear “Indian drums” and “harps”. And then he was “swept along in a river or a flood”.
Sounds like Jimmy was high on something that night.
