A new Michael Jackson track is being released in October, nearly four months after the King of Pop was found dead at his home in Los Angeles.
This Is It features backing vocals by the singer's brothers and is due to go on sale on 12 October.
It's not clear when Michael Jackson wrote or recorded the track, which will also be on a new album of his hits.
Before his death in June, the pop star had been working with artists like Akon and Will.i.am as part of his comeback.
The new song has the same name as the series of comeback shows Michael Jackson was preparing to bring to London.
Music boss John McCain, who's co-producing the new greatest hits album, said: "This song only defines, once again, what the world already knows - that Michael was one of God's greatest gifts."
The song will also feature in the closing credits of a film about the star, also called This Is It, which has been made using footage of rehearsals for his London concerts.
