During the meeting with "Lou DiMaggio" and his crew, they tell Sil and Christopher how they once killed a man named Tommy Neri. The hitman named Frank is played by none other than Richard Bright, who played "Al Neri" in The Godfather (1972) trilogy--films mentioned countless times in the series.
Meadow has a poster for the band Scout in her dorm room. In season 3, episode 9 (The Telltale Moozadell), the real-life band Scout plays the fictional band The Miami Relatives, who play on the opening night of the Crazy Horse. Miami Relatives is also the name of a song by Scout.
The song played during the ending credits is "Vesuvio" by Italian band Spaccanapoli.
