From what I understand from Broadway in Chicago, the engagement of "Hamilton" is open-ended and will play in Chicago for as long as there is interest in it.
In our millions, in our billions, we are most powerful when we stand together. TW4C unwaveringly joins the worldwide masses, for we know our liberation is inseparably bound.
