I cannot imagine that Passing Strange will ever be revived on Broadway. The show was a huge financial failure, despite mostly terrific reviews. Maybe off-Broadway.
To the poster re Black Musicals, I would propose Purlie be at the top of the list. It is a great, fun show with a wonderful score and three great roles. Multiple show-stoppers. I love A Raisin in the Sun, but just couldn't get into Risin. I did not think the score was good. It did win Best Musical, but in a very bad year. i would rather someone work on the book of Hallelujah! Baby, which also has a great score, multiple show-stopper numbers, and a real point of view. I loved it, er, 54 years ago, when I saw it twice, a lot for a kid of 16. At the time, I didn't care that the book scenes occasionally slowed the action because the musical numbers were so terrific. Fix the book scenes, i say.
