I found this interesting observation from a website, when Tony told AJ. Remember this:
"Let me tell you something, AJ," Tony Soprano said to his son in the middle of the sixth season premiere of "The Sopranos." "I don't care how close you are. In the end, your friends are going to let you down. Family, they're the ones you can depend on."

Btw, I heard Lorraine Bracco say in a brief interview yesterday, that her sister had a part in last night's show, playing a mobster's wife.

I thought maybe Eugene's wife, but this morning on Imus they had on Vito, Johnny Sac, and Eugene and they said Eugene's wife was from an acting class (not mentioning Bracco) .

So I'm not sure which part she played.
