Men at Work were an Australian rock band which 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 and keyboards; and then John Rees on bass guitar. This line up achieved national and international success in the early 1980s. In January 1983 they were the first Australian artists to have a simultaneous No. 1 album and No. 1 single in the United States Billboard charts – Business as Usual (released on 9 November 1981) and "Down Under" (1981) respectively. With the same works they achieved the same distinction of a simultaneous No. 1 album and No. 1 single on the Australian, New Zealand and United Kingdom charts. Their second album, Cargo (2 May 1983) was also No. 1 in Australia, No. 2 in New Zealand, No. 3 in the US, and No. 8 in the UK. Their third album, Two Hearts (3 April 1985), reached the top 20 in Australia and top 50 in the US.
