The first part, Millenium Approaches, opened first and played for about a year, before the second part, Perestroika, opened and began to play in rep with Millenium Approaches in the same theatre, the Walter Kerr, with the same cast. The Walter Kerr has a small backstage, and teching essentially two shows in one theatre was a nightmare, but they pulled it off, somehow. The two parts would alternate during the week, and both halves would be performed on two show days, so that you could conceivably see the whole thing on one day.
