From the wiki: “‘Down Under’ was written by the group’s co-founders, Colin Hay and Ron Strykert. It was originally released in 1980 as the B-side to their first local single titled ‘Keypunch Operator’, on a self-released vinyl single distributed only in Australia. The early version of ‘Down Under’ has a slightly different tempo and arrangement than the later Columbia release. After signing to the US label, the song was re-recorded. This more well-known version was then released on Columbia in October 1981 as the third single from their debut album Business as Usual (1981).
