The Departed music

Whats the name of the song that plays when Martin Scorsese wins the Oscar for best director. I watched the The Departed and it plays during some of the scenes. I got the official soundtrack but it didn’t have it. any help?

It’s called “The Faithful Departed,” from the score, not the soundtrack.

I’m surprised it wasn’t Gimme Shelter. That song was playing for the whole freakin’ movie.
