Trivia: Whenever the mobsters in the Sopranos pay they almost always take a wad of cash out of their pocket and pull off the top 3-4 bills and hand it over. If Tony is paying for a pizza he pulls off 3-4 bills. If he's bribing someone he pulls off 3-4 bills. No matter what the amount is for that particular situation, it's always covered with the top 3-4 bills of the cash wad.
Question: Was it Jimmy Altieri standing in the back of the crowd during the Columbus rally scene? He was killed in season one for being an FBI informant and here they probably used him as a stand in... If so, then that is some sort of mistake, because I think, it really is him.
