Fraternity were an Australian rock band which formed in Sydney in 1970 and relocated to Adelaide in 1971. 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). Their biggest local hit was a cover version of "Seasons of Change" which peaked at No. 1 in Adelaide, but nationally it was overrun by the original Blackfeather version. The group won the 1971 Hoadley's Battle of the Sounds with the prize being a free trip to London. Fraternity went through various line-ups and was renamed as Fang, Fraternity (again), Some Dream and finished as Mickey Finn in 1981.
