One of the more successful efforts at bringing theater live online, Sir Noël Coward's supernatural comedy Blithe Spirit is performed on Sept. 15 at 8 pm by actors in Prague and the UK, brought together onscreen via Zoom and the magic of digital backgrounds. The Classic Stage troupe includes Beatriz Abrisqueta, Ben Bradshaw, Marc Cram, Emma Houlihan, Rebecca Russell-Peach, Jennifer Preston, and Katerina Vecker. Free, but donations welcome. More info on how to register for the Zoom call is on Facebook.
