Paul McCartney and Stevie Wonder’s hit collaborative single “Ebony and Ivory” reached the top of the Billboard Hot 100 chart on May 15, 1982. The song went to radio in the U.S. on March 29, and was included on McCartney’s solo album “Tug of War.”During an interview with Bryant Gumble on NBC’s Today Show, Paul explained the concept behind the track.“‘Ebony and Ivory’ is supposed to say that people of all types could live together. It’s just an idea that I had heard someone say once, you know, the keyboard thing. You can play using just the black notes; or you can play using just the white notes, but combining them gives you great notes. That, I suppose, is a great analogy,” he said. The track claimed the top spot on the chart from "Chariots of Fire" by Vangelis and held on for seven weeks. It was succeeded by "Don't You Want Me" by the Human League.
