"Please Don't Go" is a song recorded and released in 1979 on the KC and the Sunshine Band album Do You Wanna Go Party. Originally written in the key of D flat, the song was the band's first love ballad, in which the subject pleads for a second chance. Shortly after the song's one-week run at number one, the group broke up and Harry Wayne Casey went solo. The song was a number-one hit on the Australian ARIA Charts, the band's fifth and final number-one hit on Billboard Hot 100 charts, and the first number-one hit of the 1980s. As the band was known as a pioneer of the disco genre, the song was released, ironically, on the same day as Disco Demolition Night in Chicago, Illinois.
