What was the specific date for the cast change in September 2016?

I attended the 24th of September performance featuring Vivienne Carlyle as Grizabella, but I don't think the listed September 2016 cast is the one I saw. I would definitely have noticed Celia Graham's name, for instance, given that I'm already familiar with her as a performer. Am I to assume that the April 2016 cast is mostly valid for this specific performance?
