The new version of “Cinderella,” initially written for TV in 1957, incorporates Rodgers and Hammerstein songs that weren’t in the original incarnation. Mark Brokaw helms. Robyn Goodman (“The Performers”), Jill Furman (“In the Heights”) and Stephen Kocis produce the show, which begins previews Jan. 25 at the Broadway Theater.
