Mario had great respect for Sinatra's voice. He was convinced to approach Sinatra in a restaurant and Sinatra did have a fit (supposedly over the scenes in the Godfather that presented him as a wimp) but Mario never spoke badly about him, and just said it was like a couple of street kids fighting with each other good naturedly. He understood, he always said, why Sinatra didn't want to be bothered while he was eating. And a few years ago, at a dinner party, Tina Sinatra told us that her father never spoke badly of Mario either. So...I leave you with the truths I know.
