Mean Streets (Scorsese) - July 17th, 2012 Pre-order

[NeoNical]

Sorry for bumping this thread but I have a question regarding one of the songs used in the film. It happens around the 90-minute mark where

[Show spoiler]De Niro beats up somebody on the street in front of people and runs away while Keitel is at his girlfriend's apartment waiting for him

. It is an Italian song, but I wasn't able to identify it for years and was wondering if anyone knew this song. Out of the thousands of films I've seen, this scene is the only time where I have no idea what the song is (That I want to listen to), and I keep thinking about this every time I think about this film or Scorsese.
