Never knowingly undersung


London's leading Gilbert and Sullivan company




Welcome to the Grosvenor Light Opera Company! We are an amateur operatic society  based in central London, focusing on the works of W.S. Gilbert and Arthur Sullivan and complementing this with other material. GLOC has a long history - with over 70 performances of G&S since its debut in 1949!

Pirates of Penzance on tour!

Thank you to everyone who supported us so enthusiastically during our very near sell-out London run of Pirates of Penzance. Check out the photos on our Facebook page here! There's one last opportunity to see us at our swashbuckling best: next week at the Gilbert & Sullivan Festival in Harrogate on 12 August. A final round of pirate sherries for everyone!


Sleeping Beauty - A GLOC Christmas Panto!

Boys and girls, we have another home cooked pantomime for all your cross-dressing needs! There's still time to get involved in the planning so do get in touch if you'd like to contribute to the script or even direct - just email admin@gloc.org.


The Open Rehearsal is on 14th September at St Gabriel's Halls, and we'll be performing on the 7th and 8th December in Pimlico. Come and join uis!                                        



We are always delighted to hear from any potential new members of the society, and have vacancies for all voice parts. We rehearse on Wednesday evenings from 6.45pm to 9.45pm at St Gabriel's Hall in Pimlico.

Iolanthe - Summer 2017

We'll shortly be issuing a call for director applications - a fantastic opportunity to direct a great company in a central London theatre!


Iolanthe was one of the first shows performed by GLOC, back in 1950 - and we're so excited to be dusting off those fairy wings again next year!


For those of you who are very organised indeed, we can even give you a few dates for your diary:

- Wednesday 15 February: rehearsals begin with auditions for principal roles likely to be the following week

- Sunday 11 - Saturday 17 June: show week at the Bridewell Theatre, Blackfriars


Make sure you sign up to the newsletter to keep updated on what we're up to next, and how to get involved.
