On April 24 1993, Fever/Bad Girl hit #1 on Billboard’s Hot Dance Music/Maxi-Singles Sales chart in America. It remained at #1 for two weeks.
Despite being marketed as Bad Girl, the release charted as Fever/Bad Girl on the Maxi-Singles Sales chart due to its b-side being the primary focus of the release in terms of content. Wisely, Bad Girl was left off of the accompanying promotional single that was serviced to clubs (on beautifully pressed transparent red vinyl), allowing it to top the Hot Dance/Club chart solely as Fever.
Today In Madonna History 
Madonna is a brilliant songwriter-When she tackles covers like the lounge standard Fever, I think she did a great job with the rendition cover!-it shows yet another side to her personality character!
Leave it to M to turn a shitty old standard into a modern disco classic.
