Remember Sutton Foster’s uproarious Princess Fred in Once Upon a Mattress? Kelli O’Hara’s shining Anna in The King and I? Here’s Broadway royalty in spades. The ladies’ program, we’re told, is inspired by the CBS special Julie and Carol at Carnegie Hall (1962), scarcely a high-water mark in the careers of Misses Andrews and Burnett, but that’s okay. Maestro Keith Lockhart, face of the Boston Pops since 1995, knows his way around a variety show, and so do these stars. —Matthew Gurewitsch
