Henry Willis Organ
The Union Chapel Organ
Built by Henry (‘Father’) Willis 1877-78, designed integrally with the architecture and installed behind the screen so that the source of the sound is not visible. The organ was inaugurated on 11 March 1878, four months after the Chapel itself was completed, with an evening recital, ticket price 1 shilling, which included three pious songs sung by Mrs Mudie-Bolingbroke.
Later in March 1878 Spurgeon was invited to preach in the Chapel, and took the opportunity in his sermon to denounce the practice of spending large sums upon "worthless noise boxes" as a sinful waste. According to him they drowned the only sound of praise God cared to hear, the human voice, and declared that he should like to see every organ smashed up. His remarks were not well received by the congregation.
The configuration is as follows
3 manuals: Great, Swell, and Choir.
37 stops: 12 on the Great Organ, 8 on the Choir, 12 on the Swell, and 5 on the pedal organ.
Action: the choir manual is worked by tracker action, and the other two manuals by Barker-lever action, a type of tracker action invented by Willis himself.
The Choir Gemshorn was replaced by a piccolo in 1909. Apart from that the organ remains in its original state, whereas nearly all of Willis' other large organs have been restored and no longer have their original action.
We are at present trying to raise money for its restoration. Which we estimate to cost £400,000.00 .Various events will be held to raise the money but donations or sponsorship of concerts are gratefully recieved. 
We are delighted to have Sir David Lumsden, Ann Elise Smoot and The Internationally renowned Carlo Curley as Patrons.
Further details of the organ including stops,wind pressures etc will be posted soon.
