Last night, the "king of pop" whispered as a youth choir sang his hit "We Are The World" at the World Music Awards in London. The singer wore all black and swayed from side to side, clapping.
The 48-year-old sang some notes, but it appeared as though his microphone was not working or perhaps that he was just singing too softly and was letting the choir carry him through it.
At the event, Jackson received the Diamond Award, given to artists who sell more than 100 million albums. The award also coincides with the 25th anniversary of the release of Jackson's "Thriller" — the best-selling album of all time.
Jackson dedicated the award "to the so many that have loved me and stayed by me throughout the 42 years I've been in the entertainment business."
It was expected that he would sing "Thriller" on Wednesday, but R&B singer Chris Brown sang it instead. A group of dancers dressed as zombies danced around him.
Jackson has been based in the Middle East since he was acquitted on child abuse charges in 2005. Asked by the AP where he has been living, Jackson replied: "All over the place."
He's working on a new album, due for release next year. Press and fans have been camped outside his hotel since he arrived in the UK.
He made a rare public appearance on May 23 to receive the Legend Award at the MTV VMAs in Tokyo.
