I watched Mean Streets the other night and was delighted to see a couple of Sopranos in there. The actor who played Melfis' ex husband was Michael and the the character called Tony was the actor who played Richie Aprille. Curiously the character played by De Niro is called Johnny Boy, which is of course Tony's dad's name. I'm sure this is a little homage by Chase to an early Scorsese classic. I think Paul Sorvino is in it as well, who was of course Paulie in Goodfellas.
