Former members include successive lead vocalists Bon Scott (who later joined AC/DC), John Swan (who also played drums and later had a solo career), and his brother Jimmy Barnes (Cold Chisel).

[8] Scott was invited to play recorder on the Blackfeather track "Seasons of Change" for that band's debut album, At the Mountains of Madness.

[8] John Freeman[9] (Levi Smith's Clefs) replaced Buettel on drums and Fraternity recorded their debut album, Livestock, which was produced by Doug Ashdown and Jimmy Stewart.

[5][18] Fraternity won the Hoadley's Battle of the Sounds – a national performance competition between the best bands representing each state – with the prize being a free trip to London.

[6][8] The same year, Fraternity performed "Love 200" at the Adelaide Festival of Arts, a Peter Sculthorpe composition, featuring Jeannie Lewis and Melbourne Symphony Orchestra.

Fraternity were renamed as Fang in early 1973, but the band had stalled and was gradually disintegrating, with the remaining members returning to Australia by the year's end.

Late in 1974, Fraternity reformed with Eyers, Freeman, and Howe joined by Mauri Berg (Headband) on guitar, Pieter Bersee[24] on violin and John Swan (Hard Time Killing Floor, Pulse, James Wright Group[25]) on lead vocals.

[6] In mid-1975, Freeman left and Swan switched to drums with his younger brother, Jimmy Barnes (Cold Chisel) joining on lead vocals.

[28] Since then Sam has been a musical director, production and guitarist for a wide array of artists including John Farnham, Goanna, The Black Sorrows, Swanee, Ross Wilson, Daryl Braithwaite, Brian Cadd, Broderick Smith, Rose Bygrave, Olivia Newton John, Tina Arena, Glenn Shorrock, Dale Ryder, Debra Byrne, Thelma Houston, Men At Work, Marie Wilson, Jane Saunders, Joe Camilleri and the Under the Southern Stars concert.

John had a short stint in Mungo Jerry before becoming a dairy farmer for Headley Farm, a polisher for Ronson Cigarettes, a rugby player and a computer programmer for Pepper Construction (Saudi Arabia) and Shell Oil.

In 2001, John was recruited by Bryon Steenson’s River Rockers and played many pub gigs and jazz and blues festivals with them until February 2007.

[2] Mick Jurd remained in England gaining employment as a sales rep and picked up some work in playing local bands.

After moving back to Sydney, Mick would start performing again with jazz player Jim Kelly playing at venues such as The Basement.

Mick’s job as a sales rep required him to move back to Adelaide in 1975, where he would join a reformed Red Angel Panic with Fraternity bandmate John Freeman.

Vince got Bon to join the band onstage at the Pooraka Hotel (now The Bridgeway) in Adelaide and there was an instant bond over Little Richard, Chuck Berry, and the shared Scottish roots of the young brothers, Angus and Malcolm.

[31] In 2021, newly unheard material uncovered by music historian Victor Marshall through his work with Fraternity and their manager Hamish Henry was released.

[44][45] In April 2023, the Grape Organisation reissued Flaming Galah on a limited edition green vinyl for record store day.

Today, Fraternity continue to be managed by Hamish Henry & The Grape Organisation Pty Ltd, alongside co-director Victor Marshall.
