- 1821. St. Mary’s opened in its original form. There was no organ. Singers and instumentalists were situated on a gallery at the west end of the church.
- 1871. The chancel was extended and the gallery dismantled. A small organ by the local Bristol company W G Vowles was provided in the north east corner of the chancel. The instrument was presented by the Misses Mirehouse following a fund-raising bazaar at the Zoological Gardens. Subseqently this organ was enlarged by Vowles and placed in a bay on the north side of the chancel.
- 1937/38. Vowles overhauled the organ and moved it to a purpose-built platform at the west end. A detached console was provided behind the choir stalls on the north side of the chancel. Despite some minor problems of coordination between choir and congregation this fine organ sounds to advantage from this position.
- 1948. Hele of Plymouth carried out cleaning and revoicing.
- 1984. The organ was cleaned and some remedial work undertaken by John Coulson.
- 2009. Clevedon Organs (UK) Ltd took over the care of the organ. During the next few years it became clear that a major overhaul of the instrument was overdue. A formal appeal was launched in September 2018 and active fund-raising commenced.
- June 2020. Anthony Hall and his team from Clevedon Organs started work on the instrument.
- The appeal remains open – see Organ Appeal section.
