What was the last song rehearsed by Michael Jackson before his death?

The last song Michael Jackson rehearsed before his death was “Earth Song.” On June 24, 2009, Jackson rehearsed for his planned This Is It concert series at the Staples Center in Los Angeles. The session continued into the early hours of June 25, just before his death. “Earth Song” was the final song he performed onstage during that rehearsal, giving the environmental anthem a tragic historical significance. Jackson rehearsed other planned numbers, including “Thriller” and “Dangerous,” which are sometimes confused with his final performance. The rehearsal footage later became part of the concert documentary Michael Jackson’s This Is It, released after his death.
