"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. The song was the band's first love ballad, in which the subject pleads obviously 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, and the band's fifth and final number-one hit on Billboard Hot 100 charts.

The song is incorrectly noted by some sources as being the last number one hit of the 1970s and the first of the 1980s on the Billboard Hot 100. In fact, it was only the number one song for the chart week of January 5, 1980, making it the first #1 single of the 1980s. It was both preceded and followed at number one by "Escape (The Piña Colada Song)" by Rupert Holmes, which dropped to number two for the week that "Please Don't Go" was number one. The B side which was called "Betcha Didn't Know That" was number one on the R&B Chart at the same time it was an Italian 92' jam, but then was re-mixed by Ajo Rabaccii From Abohar.

A soundalike cover of Double You's arrangement by the British group KWS hit number one on the UK Singles Chart for five weeks in May 1992 and reached number six on the U.S. BillboardHot 100. It was recorded and released after record company Network failed to secure UK distribution rights for the Double You version. The similarity between both versions resulted in Network paying compensation to Roberto Zanetti, Double You's producer, following legal action . The KWS version was claimed to be released in honour of Nottingham Forest (European football) defender Des Walker, who was on the verge of signing for Italian team Sampdoria.

In 2008, it was remade into a eurodance tune this time by Dance/Techno musician Basshunter.

The single was released as a single in Sweden where it reached #6.

The song was originally planned to be released in the UK as the second single on June 23, 2008. But due to technical difficulties, the release was cancelled and "All I Ever Wanted" took its place on July 7 . It had much more success than originally thought as the single reached number 2 in the UK charts.

However, despite rumours that this would be the third UK single, "Angel in the Night" was released instead and was premiered on BBC Radio 1 on August 22, 2008, during Scott Mills Friday Floor Fillers.
