The original organ was built by Henry Willis & Sons in 1871. It had four manuals and 111 stops and was, at that time, the largest in the world.
Harrisons
The Durham firm of Harrison & Harrison rebuilt the organ in two stages in 1924 and 1933, during which it was increased to 146 stops and converted to electro-pneumatic action. It was still the largest organ in Britain at that time. The 2014 Pink Floyd album The Endless River, includes a track, "Autumn '68", featuring a recording of band member Richard Wright playing the organ in 1969. In the 1970s, Harrisons refurbished the console and replaced the switchgear in the action, made minor changes to the voicing and added a roof to attempt to project the sound forward, which was not successful. One interesting note in this period is that composer Wendy Carlos featured the organ during the closing title sequence of the 1982 Disney science fiction filmTron, performed by organist Martin Neary. By the end of the 20th century, the organ was again in a state of disrepair, with an ever-increasing number of stops unusable due to leaks in the wind system, cracks in the soundboards, and other problems. By 2002, it was maintained only through "heroic efforts" on the part of Harrisons and could not be used at all without their staff present, in case of mishap. The wind chests and pipes were leaking noisily and wind pressure was insufficient to support full use. The leatherwork in the actions was also failing.
The Mander rebuild
In 2002, the organ was taken out of commission for an extensive rebuild by Mander Organs. Some consideration was given to restoring the organ to its original Willis specification, but the subsequent alterations and enlargements had made this impractical and it was felt that it should remain essentially as-is. The dryness of the Hall had damaged the soundboards, so these were replaced and new and larger wind trunks provided. The roof was removed, and the reed stops in the Great division were restored to their 1924 wind pressures. The 1970s split of the Great Organ was rationalised, effectively offering separate Willis and Harrison choruses; also a Fourniture IV was added, bringing the total to 147 stops and 9,997 speaking pipes. For a few years the organ was once again the largest in the UK, until in 2007 the distinction passed to the organ in Liverpool Anglican Cathedral. The organ was re-opened at a gala concert on the evening of 26 June 2004 with David Briggs, John Scott and Thomas Trotter playing, with the Royal Philharmonic Orchestra under Richard Hickox. The organ featured prominently in the 2004 BBC Proms series. The first recordings on the newly rebuilt instrument were by Dame Gillian Weir. The instrument has also been used by progressive rock bandMuse when playing Megalomania, originally recorded on another Willis organ, at the church of Saint Mary in Bathwick. During a live performance at the Royal Albert Hall on the 12 April 2008, Muse's frontman, Matt Bellamy, had commented that "since we're here, it would be rude not to play this beast".
