The Rockettes: Kicking up their heels for 100 years‎

Since their beginnings in Missouri a century ago, the troupe known as The Rockettes has been celebrated for their deftly-coordinated, high-precision dance moves. Since 1933, they've performed in the annual Christmas Spectacular at New York's Radio City Music Hall. Jane Pauley goes backstage with some of the dancers who have not only carried on the traditions of the Rockettes, but also have helped shape a new, diverse chorus line.
