Physical by Olivia Newton-John (1981)

"Physical" is a song by British-born Australian singer Olivia Newton-John for her twelfth studio album Physical. It was released in September 1981 by MCA Records as the lead single from the album. Recorded in early 1981, "Physical" rose to #1 on the American Billboard Hot 100 chart in November 1981 and stayed there for 10 weeks (the most of any single in the 1980s), remaining until the second half of January 1982. It reached #2 on the Radio & Records CHR/Pop Airplay chart on November 27, 1981, staying there for two weeks and remaining on the chart for 14 weeks. In terms of chart placement, "Physical" was Newton-John's most successful single in the U.S., as well as her final single to reach #1. Billboard ranked the song as the #1 single of 1982 (since the chart year for 1982 actually began in November 1981).
