"I have to tell you this, because Larry and Adam haven't heard it. Edge brought around a CD of a new tune. It's just a provision title, "Full Metal Jacket." It's the roughest, it's the mother of all rock and roll tunes. I don't know where it came from, but it's a remarkable guitar thing. You want to hear it. It's a reason to make a record. This song is that good."
- Bono, 2002
