Interviewed at the keyboard, composer Stephen Schwartz chronicles his career from college to "Wicked" and beyond. He explains how "Pippin" began as a college musical based on one paragraph in a history book and a deep love of "The Lion in Winter", and how the show that ended up as the Broadway version was completely different; tells the story of being asked to write songs for "Godspell" with only five weeks until the show's first rehearsal; plays and sings his first song ever to be heard on Broadway, from the play "Butterflies are Free"; talks about structuring a musical around a lead actor who didn't sing at all, for "The Magic Show", and whether he's disappointed that the show's technical demands have limited subsequent productions; describes how he developed and directed "Working", and why he made the decision to invite other composers onto the project; shares his feelings about the original productions of "The Baker's Wife", "Rags" and "Children of Eden", and why they met with greater success after their first incarnations; reveals that he has gone back and rewritten some of the lyrics for Leonard Bernstein's "Mass" -- with utter fidelity to every note that Bernstein wrote; gives his opinion on whether writing songs for animated films such as "Pocahontas" and "Prince of Egypt" is just like working on a Broadway show; relates how he began seeking to option "Wicked" even before he'd read the book; recounts his involvement as a producer on the musical "The Blue Flower", written by others, at American Repertory Theater -- and why he won't be producing again; and talks about what he's learned about writing for the musical theatre from his 15 years running the ASCAP Musical Theater Workshop.
