Paris told the audience: "We're very happy to be here on this special night to honour our father."After beyonce, who wore her hair in a Jackson Five-style afro, played one of the group's hits, Where You Are, saying it was the first song she had performed with her former group Destiny's Child.

Michael Jackson's brothers, Tito, Marlon and Jackie, performed at the event, which was hosted by actor Jamie Foxx and presenter Fearne Cotton."I am honoured to share the stage with the incredible performers in this line-up, and I'm certain nothing would make my brother smile bigger or brighter than this tribute concert."

However, not all the Jackson family were behind the concert.Two other siblings, Jermaine and Randy Jackson, said the concert was "inappropriate" and "ill-timed" because it was held during the criminal trial of Conrad Murray, the doctor charged with involuntary manslaughter over the star's death in June 2009.

Jackson's sister Janet Jackson also decided not to attend.And Marlon Jackson said  he respected their decision and added: "Each one of us grieves differently. We want to celebrate the positive side of his life, the positive things that he did."R&B star Ne-Yo, who gave a rendition of Billie Jean, said: "It's not about the controversy. It's not about the trial. It's not about his death. It's about celebrating his life. It's about celebrating his music."

The show was expected to have sold out.
