"Freedom Song (They'll Never Take Us Down)," due out July 2, comes after the singer surprised Bostonians with a performance at a Red Sox game in the week following the bombings. He performed Fenway favorite "Sweet Caroline" for fans and subsequently donated all royalties from its surge in sales to the One Find Boston.

"I was moved by the unity and the attitude of the people in Boston," Diamond told Billboard. "And that's really all a songwriter needs, is to be inspired. It doesn't happen very often but when it does you have to follow that muse and I did."

Diamond will perform the patriotic song for the first time on July 4th, first at the Nationals-Brewers game in Washington D.C. and again in his special appearance at the PBS-broadcast "A Capitol Fourth."
