"Pippin, Pippin" - Schwartz's college show, was originally invisioned as a mideval mystery playesque pastoral musical. The show originally ended where "Morning Glow" currently occurs, but after a suggestion from a well known producer, Schwartz rewrote the second act to explore what happens after Pippin killed his father.
After his success with "Godspell" the show (retitled "Pippin") recieved a Broadway production. Bob Fosse was brought on to helm the production, but there was major controversy between Schwartz and Fosse (it is rumored that the "annoying, young composer" in Fosse's movie "All That Jazz" was based on Schwartz.) Schwartz was still in his early twenties at the time, and he greatly disagreed with Fosse's retooling of the show (for example the song "With You" was written as a moving love ballad. When Fosse allowed the rest of the creative team into see his staging for the number, and Schwartz found that it had been turned into an orgy number he was very very upset.) Fosse ended up barring Schwartz from rehearsals. Ironically, Schwartz would later become the biggest supporter of Fosse's vision for the show.
The show was a hit, boosted by the television commercial (the first ever for a Broadway show.)
