Please Don't Go (KC and the Sunshine Band song)  "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 the song, 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, their sixth and final number-one hit in Canada on the "RPM" national chart as well as their fifth and final number-one hit on the U.S. "Billboard" Hot 100 charts, and the first number-one hit of the 1980s. "Please Don't Go" was actually part of a double-sided single, with the flip slide "I Betcha Didn't Know That" being released to R&B stations and hitting number 25 on the R&B chart. The song was the first No. 1 hit of the 1980s on the "Billboard" Hot 100. The song was also an international chart hit, reaching No. 1 in Australia and Canada and charting in Belgium (No. 8), Germany (No. 20), Ireland (No. 5), the Netherlands (No. 7), New Zealand (No. 3), Norway (No. 4) and the UK (No. 3). A sound-alike cover of Double You's arrangement was released as the debut single by the British group KWS and hit number one on the UK Singles Chart for five weeks in May 1992 and reached number six on the U.S. "Billboard" Hot 100 in October that year. In Germany, the song reached No. 7 but disappeared out of the German Singles Chart the following week due to legal issues with Double You, who covered the song before. Due to this fall, "Please Don't Go" is the song with the highest position that dropped out of the country's Singles Chart the following week. It was recorded and released after record company Network Records failed to secure UK distribution rights for the Double You version. KWS band member Chris King heard the Double You version in a club in early 1992, and, bringing together the other KWS members to form the band, decided to cover it "like The Love Affair covered Robert Knight's 'Everlasting Love' or David Parton covered Stevie Wonder's 'Isn't She Lovely'."
