Careless Whisper.

A little history

"Careless Whisper" is a song which was a worldwide number-one hit for George Michael in 1984 on Epic Records.

There was irony within the song as it was released as a solo George Michael single at a time when Wham! were at their height, yet unlike all the Wham! singles, it was co-written by Andrew Ridgeley, the other half of Wham!.
They wrote it together as unknowns three years earlier when Michael was working as a cinema usher in Watford, England.

A mid-tempo ballad with a soulful production standard and a remarkable saxophone solo, the song was issued in August 1984, entering the UK singles chart at number twelve. Within two weeks it was at number one, ending a nine-week run at the top for "Two Tribes" by Frankie Goes To Hollywood. It stayed at number one for three weeks, later going to the top of the charts in seventeen other countries, including the USA's Billboard Hot 100 in February 1985, although there it was credited as a Wham! song.
