The show underwent massive rewrites during the pre-Broadway run. All but three of the original songs were replaced.
The production had announced a Broadway opening date of December 8, 1969, with previews starting on December 3, following a pre-Broadway run at the Fisher Theatre in Detroit. At some point before previews started on Broadway, the opening was postponed to December 14. Although December 8 was a Monday, and therefore a day on which the production, which was playing a Monday through Saturday schedule, would normally give a performance, the production played no performance that night.
