Everything you need to know about Twyla Tharp's The Times They Are A-Changin'.

1. Tharp has taken Bob Dylan's musical catalogue and turned it into a Broadway show.
   
   
2. Joan Acocella, in the pages of The New Yorker (11/6/2006), summarizes it thusly:
   

   In [Tharp's] show, the owner and ringmaster of the circus is Captain Ahrab (Thom Sesma), an evil tyrant who abuses his innocent son, Coyote (Michael Arden); his kind, worse-for-the-wear girlfriend, Cleo (Lisa Brescia); and everyone else in his vicinity—namely, six Pierrot-like clowns and Cleo’s dog, whom he eventually garrotes. Then the times, they change. Coyote pairs off with Cleo, and the clowns kill Ahrab. (Or I think he died—it was hard to tell, because the scene was lit only by flashlights, but he didn’t reappear after that.) Coyote takes over the circus, which now becomes a democratic organization: everyone gets ringmaster wear. They all sing “Forever Young,” and the curtain comes down.

   
   
   

That is all.
