"I'm writing now and obviously affected by this situation in Boston, so I'm writing about it just to express myself," Diamond told Rolling Stone.

Diamond says the new tune will be broader than exclusively dealing with the subject of last week's bombing. "It's like an infestation, and I'm writing about the general situation, not just about this bombing in Boston, but what we're going through with all of these tragedies � shootings and so on and so forth," Diamond told Rolling Stone.
