The song was recorded by the former and featured as a track on the album, "This Is It" (2009), which accompanies the 2009 concert documentary "Michael Jackson's This Is It". It was premiered worldwide on Jackson's official website on October 12, 2009 four months after his death on June 25, 2009. Although Sony Music Entertainment referred to the song as a "new single" during its promotion, it was later confirmed that the song would only be sent for airplay, and not be available to buy as a single release. According to Anka, the song was recorded in 1983 and intended to be a duet between him and Jackson on Anka's "Walk a Fine Line" album under the title "I Never Heard", but these plans fell through. Thereafter, Sa-Fire recorded the track for her album, "I Wasn't Born Yesterday" (1991). The duet version of the song was featured in Anka's 2013 "Duets" album. While putting together the "This Is It" album, Jackson's demo version of the song was found. His brothers' vocals and additional instrumentation were then added to the recording. Immediately after its release, Anka threatened legal action against Jackson's estate. The estate then agreed to give Anka 50% of the song's publishing rights. [END]
