Julie Andrews and Emma Walton Hamilton, Mother-Daughter Writing Team

Singer and actress Julie Andrews began a new career when she teamed with daughter Emma Walton Hamilton to write a hugely successful series of children's books.

Their 35th, "Waiting in the Wings," about a troupe of theatrical ducks, is based on a true story. "Sunday Morning" anchor Jane Pauley talks with Andrews and Hamilton about a remarkable mother-daughter collaboration.
