Someone was humming For The First Time In Forever in the cafe at the Jerwood Space, where the musical Frozen (from which the number hails — as if you didn't know!) was in its final week of rehearsals before transferring to the refurbished Theatre Royal, Drury Lane, for technical run-throughs. The song seemed appropriate. The last face-to-face (not virtual) interviews I did, back in March last year, were with Samantha Barks and Stephanie McKeon. They play the show's stars, sisters Elsa and Anna, whose once close relationship is torn apart when Elsa exiles herself, terrified her deep-freezing powers are getting out of control.
