The song was written by Jon Bon Jovi and longtime collaborator Richie Sambora. Fairbairn pushed the group to focus on strong vocal performances and layered harmonies, often having Jon Bon Jovi record multiple takes to capture the perfect balance of power and tenderness. Backing vocals were stacked in multiple passes, giving the chorus its massive, choir-like quality that became a hallmark of Bon Jovi’s late-’80s sound.
