Men at Work were an Australian rock band best known for their 1981 hit "Down Under". Formed in 1979, their founding mainstay was Colin Hay on lead vocals; he formed the group with Jerry Speiser on drums and Ron Strykert on lead guitar. They were joined by Greg Ham on flute, saxophone, and keyboards and John Rees on bass guitar. This line-up achieved national and international success in the early 1980s.

During 1984 the band took a break as members pursued other interests. Upon reconvening later that year, tensions during rehearsals between Hay and Speiser over songwriting and the band's management led to a split in the band. Both Rees and Speiser were told they were "not required", as Hay, Ham and Strykert used session musicians to record their third album, Two Hearts (23 April 1985). Studio musicians included Jeremy Alsop on bass guitar (ex-Ram Band, Pyramid, Broderick Smith Band); and Mark Kennedy on drums (Spectrum, Ayers Rock, Marcia Hines Band). Two Hearts was produced by Hay and Ham. It was a critical and commercial failure compared to their previous albums and only peaked at No. 16 in Australia, and No. 50 on the US chart. Strykert had left during its production.  Four tracks were released as singles, "Everything I Need" (May 1985), "Man with Two Hearts", "Maria" (August), and "Hard Luck Story" (October); only the lead single charted in Australia (No. 37) and the US (No. 47). The album relied heavily on drum machines and synthesisers, and reduced the presence of Ham's saxophone, giving it a different feel compared to its predecessors. Hay and Ham hired new bandmates, to tour in support of Two Hearts, with Alsop and Kennedy joined by James Black on guitar and keyboards (Mondo Rock, The Black Sorrows). Soon after a third guitarist, Colin Bayley (Mi-Sex), was added and Kennedy was replaced on drums by Chad Wackerman (Frank Zappa). Australian singers Kate Ceberano and Renee Geyer had also worked on the album and performed live as guest vocalists.  On 13 July 1985 Men at Work performed three tracks for the Oz for Africa concert (part of the global Live Aid program)--"Maria", "Overkill", and an unreleased one, "The Longest Night". They were broadcast in Australia (on both Seven Network and Nine Network) and on MTV in the US. "Maria" and "Overkill" were also broadcast by American Broadcasting Company (ABC) during their Live Aid telecast. Ham left during the band's time touring behind the album. The final Men at Work performances during 1985 had jazz saxophonist Paul Williamson (The Black Sorrows), replacing Ham. By early 1986 the band was defunct and Hay started recording his first solo album, Looking for Jack (January 1987), which had Alsop and Wackerman as session musicians.
