Men at Work are an Australian rock band formed in Melbourne in 1979 and best known for hits such as “Who Can It Be Now?” and “Down Under”. Its founding member was Colin Hay on lead vocals and guitar. After playing as an acoustic duo with Ron Strykert during 1978–79, he formed the group with Strykert playing bass guitar, and Jerry Speiser on drums. They were soon joined by Greg Ham on flute, saxophone, and keyboards and John Rees on bass guitar, with Strykert then switching to lead guitar. The group was managed by Russell Depeller, a friend of Hay, whom he met at Latrobe University. 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 on the United States Billboard charts: Business as Usual and “Down Under”, respectively. With the same works, they achieved the distinction of a simultaneous No. 1 album and No. 1 single on the Australian, New Zealand, and United Kingdom charts. Their second album Cargo 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 reached the top 20 in Australia and top 50 in the US.
