KC & The Sunshine Band scored their fifth and final #1 hit with "Please Don’t Go," a lush pop ballad that might surprise pop fans accustomed to the group’s dance-minded disco fare. The lyrics place themselves firmly in the "without you I’m nothing" school of ballad writing as they lay on the romantic syrup with vigor: "Babe, I love you so/I want you to know/That I’m gonna miss your love/The minute you walk out that door." By the end of the song, the narrator is literally down on his knees "Beggin’ please please." The music that backs up these weepy sentiments with an appropriately ethereal melody that builds from verses that float up and down in yearning fashion into a swooning chorus that captures the song’s feverish emotional pitch nicely. KC & The Sunshine Band’s recording of "Please Don’t Go" throws out all their disco trademarks entirely to create a classic ballad sound that layers an elegant string arrangement and stately keyboards over a gentle beat. Harry Wayne Casey completes the song with an achy, mostly falsetto lead vocal that adds the right touch of emotional desolation required to sell the lyrics. Audiences truly bought into this heartbroken tune, sending it to the top of the pop chart in 1979. It remains a favorite oldie today, especially on love song shows that allow broken-hearted lovers to make call-in dedications.
