Hall & Oates' "Maneater" was knocked out of the Billboard Hot 100's top spot, after four weeks, by a song that had been virtually ignored for more than a year.
Australian pop group Men at Work's "Down Under" had been released in Australia and New Zealand in late 1981. It came to North America a year later, where it became a #1 in Canada in October 1982—a relatively rare instance of Canadian precedence, for a non-Canadian single. A month later, Americans finally began to take notice, and "Down Under" began its climb up the Hot 100, reaching #1 on January 15, 1983.
This was the second hit for Men At Work, following "Who Can It Be Now" about six months earlier. Their album, Business as Usual, topped the album chart the same week, making Men at Work the only Australian band to have a #1 single and album simultaneously.
