If you look close in the opening party at Michael's house you see Connie singing and look behind her there is Lucy Mancini.(Vincent's Mom)
Now at this point Vincent and Lucy have not made there in entrance into the room yet.You can see
her two different times before she and Vinnie
crash the party because their names were not on the list

thats pretty damn cool-- i just love this bloopers!

Outstanding catch! Another, more obvious one in III: Look at the "story" under the Immobiliare headline in the Wall Street Journal: it's a text for a word-processing manual.
