CORONAVIRUS: All UK venues closed on 16th March 2020 and there is currently no planned re-opening time though it will not be before 1st June 2020 and is most likely to be September (according to some West End producers).
Some shows have been cancelled, or closed early, but many are being rescheduled and we are trying to keep up with the changes - assume that anything posted for April to August is actually postponed or cancelled. It now looks likely that little will return till 2021.
A satire on the Parliament of the day (or of today!) - fantasy and fact collide in this, one of Gilbert and Sullivan's most popular operettas. Iolanthe, a fairy, has been banished for marrying a mortal. Her son, Strephon is in love with Phyllis a Ward of Court. The entire House of Lords has also fallen for Phyllis but she declines to marry a peer. The fairies persuade their Queen to pardon Iolanthe. She returns and is reunited with her son. The peers and Phyllis misinterpret the scene and believe that Strephon is being unfaithful. The fairies take revenge by sending Strephon to Parliament with astonishing results.
