"Give It Up" is a song by American disco and funk band KC and the Sunshine Band, although it was simply credited as KC in many markets, including the United States. Following the backlash against many disco artists on the charts at the beginning of the 1980s, "Give It Up" was a comeback hit for the band in the US. Epic Records refused to release it; however, the independent Meca Records label showed its support and "Give It Up" peaked at number 18 on the US Billboard Hot 100 in March 1984. "Give It Up" had been an even bigger hit in the United Kingdom several months earlier, where it had hit number one on the UK Singles Chart for three weeks in August 1983. It went on to become the 18th best-selling single of the year in the UK. It was the last of the band's hit singles in the US and UK, and the most successful of its ten UK hits. "Give It Up" also peaked at number two in Belgium, number three in Australia, and reached the Top 10 in several other markets.
