Who we are!

We believe musical theatre is for everyone and should be at the heart of our Colchester community.

We are an amateur theatre company that is there for everyone and anyone who wants to perform or help to put on amazing shows.

Colchester Operatic Society was founded in 1924 and we are one of the region’s oldest musical theatre companies performing annually to rave reviews. Over the years we have put on 128 shows/concerts involving over 8,500 cast and crew.

We currently produce a main show in the early part of the year, running for two weeks at The Mercury Theatre and a summer concert, which has been performed at a variety of smaller venues, in and around Colchester.

A huge number of our young people have gone on to form successful careers within the theatrical industry. Many of these are currently performing on West End stages and on your TV screens! To find out more about our CO2 youth group click here.

For many of our members it is being part of an exciting theatrical project that interests them. If you love acting, dancing, singing or assisting in other aspects of theatre productions, there is something for you in COS.

We pride ourselves on being community based. Whatever your age, gender, ethnicity, experience or ability, Colchester Operatic Society offers challenging, rewarding and above all FUN activities for anyone with an interest in musical theatre. To us, inclusion matters.
