Michael Jackson and Paul McCartney first met and became friendly in the mid-1970s, when, according to Jackson, McCartney tried to sell him a song, “Girlfriend,” for Jackson’s upcoming solo album. Although it took a couple of years (and McCartney released the song first with Wings), the two hit it off, and over the next few years, they collaborated on a number of duets. The lead single off of Jackson’s smash album, Thriller (1982), was “The Girl Is Mine,” a duet he penned while watching cartoons with McCartney. Likewise, McCartney’s album Pipes of Peace (1983) had two songs featuring Jackson, “The Man” and “Say Say Say.” The two superstars even filmed a music video for “Say Say Say,” playing traveling vaudevillians who peddle their “Mac and Jack Wonder Potion” to unsuspecting townspeople.
