By the Numbers the only thing Jitterbug! needs is Julie Taymor and an animal to be a hit Broadway show

So, going by these stats compiled into this Infographic by Ken Davenport of The Producer's Perspective, Jitterbug! has the potential for greatness by sharing 7 of the following attributes of the 20 Top Broadway Musicals:

1. 40% have only one word as the title. Yes, Jitterbug! fits a marquee better than its original title: Once Upon A Time in Harlem. And that exclamation point can't hurt either.
2. 40% are American.
3. 35% are Period.
4. 8 are based on movies (Jitterbug! is based on a screenplay).
5. 4 have books attached (the Jitterbug! textbook comes with free Educator Manuals based on the National Core Arts Standards in Music (Composition and Ensemble strands), Dance, Theatre, Literature, and History/Social Studies) with sections on Empathy.  There is also a truncated Radio Version available (Once Upon A Time In Harlem). 
6. 3 are "Jukebox Musicals," ie, the music isn't original to the libretto but is harvested from hit songs assembled to tell the story. Jitterbug! uses 17 from The Great American Songbook, ranging from The Buck Dancer's Lament (1907) to Ornette Coleman's The Artist in America (1972) with all Performance Rights secured. That said, Jitterbug! differs from a jukebox musical in that it's a realistic drama first. None of the main characters break out into song but they are required to dance really, really good. Hence the term coined by Jazz Dorsey, Dramaturg and Founder of the African American Playwrights Exchange (AAPEX), to describe this drama with music and dance: Dancical.
7. Only 1 is original (unless Jitterbug! gets made into a movie first).

Getting Julie Taymor or any of those other directors might be a stretch but finding a tap dancing dog that can jitterbug too may be equally difficult. We'll see.
