On this day in music history: January 5, 1980 – “Please Don’t Go” by KC & The Sunshine Band hits #1 on the Billboard Hot 100 for 1 week. Written by Harry Wayne Casey and Richard Finch, it is the fifth and final chart topping single for the R&B/Disco band from Hialeah, FL. Marking a dramatic shift away from their classic uptempo dance sound, the lush ballad is issued as the second single from the bands’ sixth album “Do You Wanna Go Party?”. Released in July of 1979, the single begins a very slow ascent up the chart. Entering the Hot 100 at #86 on August 25, 1979, it climbs to the top of the chart nineteen weeks later. Taking nearly five months to the reach the summit, it makes “Please” one of the slowest climbing singles to ever reach the top of the Billboard Hot 100. “Please Don’t Go” is also the first number one single of the 1980’s, temporarily interrupting Rupert Holmes’ three week run at the top with “Escape (The Pina Colada Song)”. “Please Don’t Go” becomes a hit again in 1992, when it is covered by British dance pop group K.W.S. (#1 UK Pop, #6 US Pop), changing the pop ballad to an uptempo dance track.
