Iolanthe - Summer 2017

GLOC is performing Iolanthe at the Bridewell Theatre in Blackfriars, central London, from 14th - 17th June at 7.30pm, with a matinee at 2.30pm on Saturday.


Meet Strephon, a lowly Shepherd, and Phyllis, the ward of the Lord Chancellor. They're madly in love. There's just one problem - Phyllis' guardian won't let them get married, and the whole House of Lords wants to marry her instead. Oh, and Strephon's half-fairy, and his fairy family will turn the country upside down to make him happy. So, nothing can possibly go wrong then...


Iolanthe is a hilarious classic of the G&S canon, with brilliant music and sharp commentary on the House of Lords that remains as relevant now as it was in 1882.
