Fosse got author royalties from Pippin and also got a share of the profits of the production in addition to his director/choreography royalties.
In the 70s NO ONE (note caps) got along with Stephen Schwartz and any number of production people kept him out of their theatres. This is one of the major reasons that after Working he sort of went under the radar until he started doing songs for Disney movies about 15 years later.
There was an uncontrolled ego on the loose after Godspell, Pippin and Magic Show. A lot of people shed no tears when Baker's Wife and Working failed.
The best critical dissection of Pippin was along the lines of a tiny little musical wrapped up in a great big shiny package.
Shortly before production began a big backer pulled out (200Gs out of a budget of 750Gs). Rather than delay, there were some major cuts made in the budget, much of it in the scenery which is why there is that 2D set made of rope at the show's start and then there really isn't much big scenery afterwards. The lighting is the design star of the show. Fosse, producer Stu Ostrow, Assoc Producer Kennedy Center and the other backers had the last laugh when they got higher profit distributions.
I never wanted to see the video having seen it on stage about 6 times. It is a theatre piece and probably wouldn't work in any other medium.
