Elton John and his partner, David Furnish, will sit down with Barbara Walters for their first major U.S. Television interview since the birth of their son, Zachary, this past Christmas. In the interview, John and Furnish will discuss why they wanted a child, how they kept the baby a huge secret until he was born, and how fatherhood has changed them both. They will also introduce Walters to Zachary, their four-and-a-half-month old son.
