Friends and family, as well as celebrity wedding guests, offer anecdotes and commentary on the lives of the famous couple who died in a plane crash in 1999.

“On an island off of Georgia we came together on this 18th century plantation. In this dirty, dilapidated, shuttered church next to a pig sty,” says a friend of the famous couple in a preview of the special.

“No air conditioning, very little power on the island. It was the best place for them to host a secret ceremony.”

He adds: “Nobody would have expected that three years later we'd be at another church for another reason.”
