Broadway: The American Musical conclusion, 9-11 p.m., Channels 48, 16.

When West Side Story opened in 1957, it made fresh demands. The duties of director and choreographer were combined in one man, Jerome Robbins; actors had to be great dancers and vice versa.

Robbins continued to triumph - especially with 1972's Fiddler on the Roof. Others followed his visual approach, peaking when Julie Taymor directed and designed The Lion King.

There have been other twists and turns, many of them contradictory.

Andrew Lloyd Webber and Stephen Sondheim created virtual operas with music flowing throughout the story. Still, Jerry Herman (La Cage Aux Folles) and Mel Brooks (The Producers) proved there's still a place for comedy and for simple, enjoyable tunes.

Big shows, with $10-million price tags and corporate producers, ruled. Still, the late Jonathan Larson's Rent showed that Broadway could still be a personal experience.

This terrific documentary closes with Wicked, a mega-budget hit.
