Now The Tingle, As I think of it, is rare. I go to the theatre four nights a week and months go by without any sign of it. I was so surprised that I made a note: “7.49: The Tingle!” It wasn’t the only time I felt it over the next two and half hours, each time when Harriet Jones, who was playing Christine, was singing. She deserves to be a star and I count myself lucky to have seen her.
