Primary Sources: The 1980s: Charles & Diana Marriage

A rare and revealing interview with the man who will be king: Prince Charles, the 56 year old heir to the British throne. In this interview conducted just before he and his new wife joint visit to the U.S, the Prince tells Steve Kroft about his efforts to stay relevant and to preserve tradition in his country. Steve Kroft reports.

"The broadcaster who interviewed Prince Charles and Princess Diana in 1981 revealed the then-20-year-old girl looked 'out of her depth' while watching it again. "

"In a break with tradition, Lady Diana Spencer will not promise "to obey" Prince Charles when they marry at St. Paul's Cathedral on July 29, Buckingham Palace announced Wednesday."

"Queen Elizabeth II, Princess Margaret, Princess Anne and a long line of royal brides before them have included the word ''obey'' in their wedding vows, as prescribed in the Anglican Book of Common Prayer dating from 1662. But Lady [Diana Spencer] has chosen to follow the new ritual of the Church of England, and she will promise in the ceremony at St. Paul's Cathedral only to ''love him, comfort him, honor and keep him, in sickness and in health.''"
