"Who Can It Be Now?" is the breakthrough single from Men At Work's 1981 debut album Business As Usual, featuring a memorable saxophone solo from multi-instrumentalist Greg Ham. The track, written by vocalist Colin Hay, is set in E major with a rock feel at 130 BPM. Ham's tenor saxophone solo arrives after the second chorus, its slightly anxious melodic character perfectly complementing the song's theme of paranoid suspicion about an unexpected visitor. The solo has become one of the most recognizable saxophone moments in 1980s pop music. Business As Usual was a phenomenal commercial success, reaching number one on album charts in multiple countries and making Men At Work one of the biggest bands in the world during 1982-83. The Australian group's blend of new wave energy, pop hooks, and reggae-influenced rhythms created a distinctive sound that stood apart from their contemporaries. Ham's saxophone and flute work throughout the album was integral to the band's sonic identity, providing melodic counterpoints that elevated the songs beyond standard guitar-driven rock. The song's quirky arrangement, with its syncopated keyboard pattern and Ham's sax punctuations, captured the nervous energy of early 1980s new wave while maintaining an accessibility that propelled it to the top of charts worldwide.
