For the first twenty years of the work a harmonium was used to accompany the singing. Then in 1885 a pipe organ, supplied by London firm J B Cramer, was purchased for £100 (£12,600 today). Cramer's existed from 1861-1921. On October 1, 1885, this organ was used for the first time in a service. Dr Edward B Underhill (1813-1901), secretary of the BMS was the preacher.
In 1908, some money from the legacy of Willesden and Hampstead businessman William Richard Rickett JP (1830-1907),was used to replace the first pipe organ with the one that currently stands defunct in the church today. It cost £250 (nearly £30,000 in today's terms). It was made by Rest Cartwright of Haringey.
The organ was repaired from time to time, a big fuss being made when it was overhauled in 1950, the event subsequently being celebrated with a special organ evening.
