Theatre Organ Society of Australia

The Theatre Organ Society of Australia (TOSA) is an Australian non-profit organization, that promotes the preservation and presentation of theatre organs. Each state has its own division, which is a free standing and independent body.
History.
After the silent film era was over, and many theatre organs were getting scrapped, many small groups of enthusiasts in the USA and the UK got together to try to preserve what they could of the remaining instruments, to save their legacy. Various societies formed during the 1960s and still function today, based in Brisbane Qld, Sydney NSW, Canberra ACT, Melbourne Vic, Hobart Tas, Adelaide SA and Perth WA. There are other groups not named as a formal "division" but which still share knowledge, experience and other functions in preserving and presenting theatre pipe organs across Australia.
Rod Blackmore, the longest-serving member of TOSA's NSW division, edited its journal "The Diaphone" from 1963 until its cessation with Vol 7, No 4 (Nov 1969).
Current activities.
Throughout the year, many concerts and other activities are sponsored by TOSA, and promoted through their website at tosa.net
