Just seeing the words "Michael Jackson" and "Paul McCartney" placed next to each other would have sent chills up any music fan's spine back in 1983, when "Say, Say, Say" was released. The super duo's hit spent six weeks atop the Billboard Hot 100 and was the second of two duets from the pair, following "The Girl Is Mine" (No. 2 on Jan. 8, 1983). The stars drifted apart after 1985, when Jackson purchased the massive ATV catalog of songs (which included the majority of the Beatles' catalog). McCartney was later cool to Jackson, but after the latter's passing in 2009, he issued a statement about the King of Pop: "I feel privileged to have hung out and worked with Michael. He was a massively talented boy man with a gentle soul. His music will be remembered forever and my memories of our time together will be happy ones."
