In 1983 the late Michael Jackson joined forces with ex-Beatles star Paul McCartney to create a song. And Say Say Say was born. The new hit exceeded its predecessor’s (Billie Jean, I’ll Be There, Beat It) success, staying in the American top 10 for several weeks, also being Nr.1 in the Billboard Hot 100 for 6 weeks, thus making it the most popular MJ song in the US! You don’t say!
