This was followed by an address by Reagan aboard USS "John F. Kennedy" and a 30-minute fireworks display and concert, scored and conducted by Joe Raposo, the highlight of the night. It was the largest fireworks display in American history, and at the time the largest in the world. The display included 22,000 aerial fireworks, launched from 30 barges and other vantage points, in addition to 18,000 set pieces. It was co-produced by four family-owned fireworks firms, namely the Zambelli, Grucci, Santore and Sousa families.
