The album track features ambient noise recorded in Sydney's Kings Cross district, including the sound of motorbikes, strip club spruikers and crowds of drunks, recorded by author Don Walker on a portable stereo. Also recorded are Walker's favourite busker and a snippet of Dragon's "Rain". This version appears on later greatest hits album and is most frequently played on radio. The original single version omits the street sounds. Although Walker was unhappy with many of the songs from the "Twentieth Century" album, he later said he was particularly pleased with the production on "Saturday Night", which he was mostly responsible for.
