In 1972, George Duncan and Roger Jones were thrown into a river in Adelaide by a group of men believed to be police officers, resulting in Duncan's death. Jones refused to identify their attackers out of fear for his life. Two police officers were charged but acquitted, the case was said to have been the subject of a government cover-up. An independent police report described it as the result of a "'high-spirited frolic' that went wrong".

Gaby oh Gaby

"Gaby oh Gaby" is a song first published by Alain Bashung. Written by Boris Bergman with music by Bashung, it was published as a single in 1980 on Philips, with "Elle s'fait rougir toute seule" as the B-side; the single became a huge hit in France, therefore the song was included on the album Roulette russe in a reissue nicknamed Nouveau couplage, on the CD reissue of the next album, Pizza. When the single came out, Bashung had been a singer for fourteen years; the singles recorded between 1966 and 1977 were all commercial failures and his first album, Roman-photos, issued in 1977, which he would disown, was one as well. "Gaby oh Gaby" revealed the singer to a larger audience. The song was shown in numerous TV shows on the evening and during the night, broadcast on radio, was in first page of the newspaper Libération; however if he admits that this hit saved him at the time, Bashung was caught off-guard by this unexpected success. On the album Play blessures issued in 1982, Bashung sang about this on his song "J'croise aux hybrides": "J'dédie cette angoisse à un chanteur disparu, mort de soif dans le désert de « Gaby ».

Respectez une minute de silence, faites comme si j'étais pas arrivé..." On May 19, 2009, the Gold Disc of the original 45rpm was sold on auction in Paris by its owner, a collector. It was sold for €3717; the song is included in a list of 3000 rock classics in the book La Discothèque parfaite de l'odyssée du rock by Gilles Verlant, who calls the track "Gaby oh Gaby" one of the "summits of the decade" alongside the next single "Vertige de l'amour". Boris Bergman, the lyricist, explained after the death of Alain Bashung: "C’est un texte sur les minorités, ceux que «la différence» fait tomber dans les puits de solitude. Le petit Ashkénaze que je suis, le Kabylo-Alsacien qu’est Alain, s’en doutent depuis leur première rencontre avec l’autre: "Gaby" est aussi un hymne caché à la solitude de l’homo qui ne connaît pas encore l’existence du PACS."
