Welcome to Mostly G&S, a group based in the Reading, Berkshire area that enjoys singing operetta with specific emphasis on the works of WS Gilbert and Arthur Sullivan, but also with interests in performing the works of composers such as Franz Lehár, Johann Strauss and Jacques Offenbach.

We have developed a style of performing concert versions of the shows, in a semi-staged way that allows the story to be conveyed while the music really shines through.

Please take a look around our website to find out more about us and our upcoming shows.

Our Next Show

Have been involved for a few years and enjoy the concert concept as opposed to a full blown show, which I also like. Always need more men. Come and join an eclectic group, if you have enthusiasm and a desire to sing- David Wilson


We are always delighted to welcome new members. 

It is not essential to be able to read music and be prepared to make some new friends and have fun!

Take a look at our JOIN US page to find out more information.

Very welcoming and friendly group, great fun performing G&S in a lovely intimate theatre - what's not to love!- Jenny Spence
