In 1983, Michael Jackson
recorded "This Is It," a song he composed with songwriter Paul Anka
, and when rehearsal footage for Jackson
's planned concert residency at London's O2 Arena was turned into a tribute documentary in the wake of his death, the previously lost tune became the movie's title number. Selections from Michael Jackson's This Is It
is an EP drawn from the film's soundtrack album; it featured the single version of "This Is It," an alternate mix featuring an orchestra, rare demo recordings of "She's Out of My Life," "Beat It," and "Wanna Be Startin' Something," and Jackson
reciting his poem "Planet Earth."
