Longtime Bob Fosse collaborator and one of creators of Fosse Ann Reinking joined Ben Vereen (who made a splash on Broadway in Fosse's Pippin) in the Broadway company March 2. Reinking continues in her dance track, which includes the numbers "Big Spender," "Mein Herr" and a new duet version of "Dancin' Dan" ("Me and My Shadow") with Vereen through April 1.
