to the church by the presiding bishop of the Anglican Church in Japan, Bishop Michael Yashiro, on 9 June 1950 in the years following the Second World War. It serves as a memorial to Sister May Hayman, a staff member at the Canberra Hospital and a parishioner at St John's. Sister Hayman was killed by Japanese soldiers in New Guinea whilst serving as a missionary and nurse during the war. In September 2014, the Bishop of Kobe (Andrew Yatuka Nakamura) attended a service at St John's in memory of Sister Hayman and to celebrate the modern Australia-Japan relationship. Music St John's has had several organs installed throughout its history. The present pipe organ, built by Ronald Sharp and installed in 1981, is the builder's last major instrument. It is a 2-manual tracker action instrument located in the west gallery, with a case made of Western Australian jarrah and tin facade pipes. Sharp built many other significant Australian pipe organs including the Sydney Opera House Concert Hall organ and organs at St Mary's Cathedral, Sydney, the Canberra School of Music, the Perth Concert Hall and Knox Grammar School. In the mid-1970s, the work was undertaken to extend and strengthen the gallery in order to accommodate the new organ. St John's first organ was an English-built, single manual tracker, installed around 1862. It is now located at St Luke's Anglican Church, Deakin. A second instrument was built in 1933 by Hill, Norman & Beard had five extended ranks with electro-pneumatic action. It was sold in 1979 to a private owner. St John's Choir is a four-part volunteer choir which sings at the traditional Book of Common Prayer services of Mattins and Evensong. The choir is usually accompanied by the organ at Sunday services. At special occasions such as weddings and church festivals, accompanying instruments can include the flute, trumpet and keyboard. Bells The chime of eight church bells were donated by Governor-General William Sidney, 1st Viscount De L'Isle and mark his term of office (1961–65). They were presented as a memorial to his wife Jacqueline. The bells were cast by John Taylor & Co—the same foundry at which the bells of the National Carillon were cast—and were installed in 1964. They range "in weight from 2 to 13 hundredweight and in diameter from 3 feet 4.5 inches to 1 foot 9 inches". The bells are rung in the English change ringing tradition,
