2020 was the season that wasn't because of CDC lockdown recommendations. The show which were on based were tentatively rescheduled to 2021 and then rescheduled to 2022 where the shows finally went on.
Ironically the first rehearsal of Beauty and the Beast was to be the last one until 2022 when the saying that 'the show must go on' came to fruition. One incredible thing was that so much of the cast came back two years later.
