A new Michael Jackson song has been released, the first since the ‘King of Pop’s’ death.The single ‘This is it’ features backing vocals by two of the star’s brothers, but it is not known when the track was written and recorded. In London, devoted fans waited overnight to get their hands on the new CD. “This is the first ever premier of the new song they are going to show it for the first time. I thought I want to be a part of history and I’m really excited to be one of the first people to hear it,” one fan said. Jackson’s album, also called ‘This is it’, goes on release later this month.
