I recently read an interview with Jonathan Bailey (''Bridgerton'' and Olivier winner from the London ''Company''), and he says his current guilty pleasure is looking up flash-mob versions of musical numbers. He cited an ''amazing'' one, set in an ''American mall.'' I'm assuming it's got to be the one that Orlando Shakespeare Theater did in 2014. They promoted their production of ''Les Miserables'' with a flash mob of ''One Day More'' at a local mall. And boy, did you hear these people sing. The cast is astonishing, and so were the acoustics. It's racked up over 10 million views. Bravo!
