Who Can It Be Now was released in 1981 by Australian band Men At Work as a single from their debut album Business as Usual, with the saxophone part played by Greg Ham. The song became an international hit in 1982 and its anxious lyric about wanting to be left alone helped the riff stick in popular culture. Decades later the opening was clipped for memes and short videos, where the who can it be now saxophone meme signals suspicion about an unseen visitor.
