This Facebook post by Folk Alliance Australia includes a comprehensive list of John's musical achievements.

Folk Alliance Australia presents “Services to Australian Folk Music Award 2021” to John Thompson.

Folk Alliance Australia is currently considering the Awards we present to members of our community and are in the process of launching a program of national folk awards.
When singer John Thompson’s ill health was called to our attention we moved to recognise his contributions to folk music by making him the inaugural recipient of our discretionary Award for Services to the Folk music community. Sadly this award was made on the day of his passing.

John Thompson was an acclaimed singer and collaborator, a glorious interpreter of traditional songs, a lover of Australian folk music in all its guises, and an artist who will make you laugh. His biography (on the Cloudstreet website) reflects not only his musicality, which embraced many genres, but his wry humour. There you will also find magical recordings of his beautiful singing.
Folk Alliance Australia join his friends and colleagues in valuing all he has done in our community, festivals, events and music sector.

John Thompson 1964 - 2021

John’s earliest musical memories are of sing-alongs around the family piano in the Brisbane suburb of Moorooka. As a result, a disturbing number of music-hall favourites formed his early repertoire (including traditional numbers like, “If You’re Irish, Come Into the Parlour”)

In 1975, John joined the St. Stephen’s Cathedral Boys’ Choir in Brisbane. Singing with them over the next six years, he developed a love of harmony singing and unaccompanied vocals.
After leaving both the choir and school in 1981, John’s life was relatively music-free until he walked into the New Exchange Hotel one Saturday afternoon in 1983 to find a traditional folk session in full swing. He stayed on and has maintained his involvement in Brisbane sessions ever since.

John’s next musical move was into busking, with the madness of Contraband in the Queen Street Mall. Away from the street, John joined a second group, which quickly evolved into No Right Turn. Their tight harmonies and political punch made them a mainstay of the Brisbane folk scene.
After No Right Turn, John was a founding member of One Step Forward, developing his trademark harmonies with Maree Robertson and Ann Bermingham.

While all of this music was going on, John was also studying law at the University of Queensland and working with the Legal Aid Office. In 1992, his legal work took him to Townsville where he launched himself into the local folk scene.
One Step Forward continued to perform at festivals around Australia and in 1994 played at the National Folk Festival in Canberra. John’s unique vocal style and strength earned him the inaugural Lis Johnson Memorial Award for Vocal Excellence.

It was in Townsville that John started to perform with Martin Pearson, their madcap adventures in satire and storytelling evolving into Never the Twain. (A difficult-to-describe duo; they managed to come up with ‘like two ping pong balls in a washing machine’ )

It was also in Townsville that John met and fell in love with Nicole Murray. In the early years of their relationship, they each performed with different groups before Maree Robertson asked them to support Chris While and Julie Matthews at their first Brisbane performance. It went well and shortly after Cloudstreet came into being as a vehicle for their ongoing collaborations.

Three years of festivals and two albums later, in 2003 John left the legal world and took up fulltime performing. Cloudstreet travelled to the UK for the first time that year and threw themselves into the folk scene there. As well as ten trips to the UK, touring has seen them
perform around the globe, with performances in Japan, the USA, New Zealand, Denmark, Morocco and Germany, and performances at dozens of festivals and clubs around Australia.

John played guitar, English concertina and whistle and also began learning trombone and violin. Singing remained his passion and his remarkable vocal range provided some enthralling listening in Cloudstreet’s arrangements. On top of singing with Cloudstreet, John performed as a debater, master of ceremonies, songwriter, and arodist. He was also a registered marriage celebrant and the principal of Australian Ceremonies. In 2009, he toured the UK with the legendary Spooky Men’s Chorale.

In 2012, John was invited to join the Australian tour of War Horse, the National Theatre of Great Britain’s worldwide phenomenon. He played the role of the Song Man from December 2012 to the conclusion of the tour in August, 2013.

Other recent projects have include recording with One Step Forward and creating a one-man show and album, The Great War.
In 2015, John was awarded a QANZAC100 fellowship by the
State Library of Queensland to undertake a research and song-writing project around the conscription debate in Queensland in the First World War, and produced a show and album called Censors, Conscripts and Queensland.
He co-founded the Maleny Celtic Winter School, an annual school for traditional music which ran for 7 years, and played Scottish music for
community dances and weddings with The Ceilidh Clan for many years.
After expanding to become a trio with Emma Nixon, Cloudstreet recorded two more albums in 2015 and 2019.
John’s final concerts included a gala performance with Cloudstreet and a small orchestra at the State Library of Queensland in 2019, and taking the orchestra to his beloved Woodford Folk Festival that year.

He was diagnosed with advanced cancer after Cloudstreet’s 2017 UK tour. John died on 4 February, 2021.
