Background[]
The original recording was made sometime during the HIStory sessions, with this version being recorded in 1996, both done at The Hit Factory. The tape itself dates back to August 27, 1996. The master tape was formerly auctioned on gottahaverockandroll.com until it was eventually taken down by the Michael Jackson Estate.[1] It's currently unknown if Jackson had recorded the song for any actual project, although considering the period, it was likely intended for BOTDF.
