Anu and Kelly performed "Last Train" as a duet, which was issued on 20 September 1993 and peaked at No. 93 on the Australian ARIA Singles Chart in the following month.

In 1986 Paul Kelly wrote "Last Train to Heaven" as the lead track of the debut album, Gossip, by his group Paul Kelly and the Coloured Girls. The album was issued in September that year on Mushroom Records while Kelly was living in Sydney.

Early in the 1990s Anu and Kelly met each other when she was a dancer with Bangarra Dance Company and he was touring Queensland. During 1992 while still at her dance company Anu started singing backing vocals with Neil Murray's group, The Rainmakers. Murray encouraged her to sing lead vocals and she signed with the White Label, a subsidiary of Mushroom Records. By early 1993 Kelly had relocated to Los Angeles and signed with Vanguard Records to tour the United States as a solo artist.

Kelly had stayed in the US for nine months and upon his return to Australia he was contacted by Mushroom Records to collaborate with Anu. With record producers, Angelique Cooper and Peter Crosbie, Kelly co-wrote "Last Train", as a dance remix of "Last Train to Heaven". As a duo Anu and Kelly recorded "Last Train" with Anu on lead vocals, Kelly on acoustic guitar and backing vocals and guest artist MC Opi's toasting. Anu praised Mushroom Records "[t]hey were really helpful in giving me my first song to record (Paul Kelly's 'Last Train'), and there was always the idea of we're going to get together and write songs — collaborate with other people for experience sake".
