Chance: That tune, they been playin' it all day. What is it? Dude: Oh, it's some Mexican piece. I heard it farther south.... Colorado: Well, they call it "The Deguello," the cutthroat song. The Mexicans played it for those Texas boys when they had them bottled up in the Alamo. Played it day and night 'til it was all over. Now do you know what he means by it? Chance: No quarter, no mercy for the loser.
