Turnbull may be the best person to answer this. But when I was first getting into the Godfather in 2001/2002, I watched the Saga/chronological version on AMC. I may be wrong, but I swear that the dialogue where Woltz says the "daigo, guinea, wop" line was in a different scene than the theatrical version. Maybe it wasn't the Saga, but it was something because my wife and I both remarked that we had not remembered that dialogue in any scene beside the production studio. I want to say the dialogue took place at the dinner Woltz & Hagen had.

Am I just remembering incorrectly? I have not viewed the Saga in at least 4 years, so I have never been able to rewatch for an answer to my question.
