KC and the Sunshine Band hit the top of the Billboard Hot 100 chart with “Please Don’t Go” on January 5, 1980. The track was released as part of their sixth studio album, “Do You Wanna Go Party,” and marked their fifth and final number one hit single. When “Please Don’t Go” hit number one, it bumped "Escape (The Piña Colada Song)" by Rupert Holmes from the top spot. Casey and company held on for one week at the top before Holmes reclaimed that top spot. The track signaled a break from Casey’s disco past:“I was honestly getting a bit bored by disco. I love that type of music but I thought people were starting to think there was no depth to me, that there was no variety,” he admitted to Billboard.
