The organ with resprayed casework pipes in brilliant gold at Southend High School for Boys

Welcome to the website of the Old Southendian Organ Society (OSOS), a society set up to protect and enhance the future of the War Memorial Organ at Southend High School for Boys.

We aim to assist the School in supporting current pupils with their organ endeavours, and further enhance the opportunities available to them through the friendly community of past School Organists and Old Boys.

OSOS was formally constituted on April 25th 2014 at a meeting at Southend High School for Boys, and is affiliated to the Old Southendian Association. We are a charity in England and Wales (registered charity number 1173343).
