When the production opened, there was no intermission. About 10 minutes before performance time, an announcement would be heard through the speakers warning the audience that the running time of the show was more than two hours and there was no intermission so they should now do whatever they needed to do before the performance started.
An intermission was added for the London production, reportedly because it was believed that the London theatregoing public would want one. The intermission was placed after "Momma, Look Sharp." To their surprise, the creative team found that they preferred the show with an intermission. On July 23, 1970, an intermission was soon added to the Broadway production. It seems that between the London opening on June 16, 1970, and July 23, an intermission was added to the national tour.
