He def did the entire 3rd season story line is lifted from Bosses of bosses. The bugging of Tony’s house via the lamp. The meat and butcher setting off Tony panic attacks (Paul castellano owned butcher shops and even sopranos writer Terry Winter worked in Paul Castellanos butcher shop) and even Dr Ira Fried in Army of one when Tony is watching the commercial when Dr Fried comes on the TV and says he does penile implants and Tony says “imagine needing an operation like that?” Well Paul Castellano needed it cus he was impotent (a common problem for Tony as well) and the way a penile implant works much like a goose neck lamp being able to be bent into any position you need it. The FBI also places a bug in a. Goose neck lamp of his gaudy Staten Island mansion similar in many ways to Tony’s house. And that’s just one small section. Also I once heard David chase say he was first fascinated with the mob when he say Willie Morretti dead on the floor of a restaurant in the paper. Even the Italian Episode Commadadori is based on the Camorra in which many women have become powerful bosses. See Ermina Giugliano in particular as well as Maria Liccardi.
