"According to Giddins, Bing told his son Gary to stay away from alcohol ('It killed your mother') and suggested he smoke pot instead. Gary said, 'There were other times when marijuana was mentioned and he'd get a smile on his face.' Gary thought his father's pot smoking had influenced his easy-going style in his films."I did not know this!
Nor did I know he had dated Grace Kelly, and a playboy playmate before he married his second wife (after the death of his first wife).
It is even said that he was a cruel father to the children of his first marriage---but a wonderful father to his second family.
