The Soprano's

It’s been confirmed it is NOT Phil’s nephew and Bobby never says “everything just goes black”

Sorry, you’re right.

Excerpts from an interesting article:

"The “Members Only” guy was played by the owner of a real-life pizza parlor, Paolo Colandrea. Schaffer denied reports that Colandrea had appeared earlier in the series as the nephew of Tony’s New York gang rival, or that there ever was such a character. "



Moreover, he said the man in the “Members Only” jacket could be interpreted as a symbolic reference to membership in the mob. "



The biggest hint, according to a consensus taking shape on the Web, is a scene from an earlier episode in which Tony and his brother-in-law, Bobby “Bacala” Baccalieri, muse about what it feels like to die.

“You probably don’t even hear it when it happens,” Bobby says while they sit fishing in a small boat on a lake.

“I think that is one of the most legitimate things to look at,” Schaffer said when asked about theories that the Bobby Bacala flashback was meant to foreshadow Tony’s death.
