Michael Jackson Vienna Tribute Concert Postponed

Jermaine Jackson's planned tribute concert to his late brother Michael has been postponed. The concert -- originally planned for September 26, 2009 in Vienna, Austria in front of Schoenbrunn Palace -- will now be held in June 2010 at Wembley Stadium, London.

All ticket holders will receive a refund for the tickets that they have purchased for the Vienna concert.

According to Jermaine: “Now we have 8 months to put this monumental show together and not just 8 weeks. Despite the short amount of time we would have been able to stage a great show, in keeping with Michael’s high standards, but numerous stars were just not able to change their schedules to make a live appearance at the Vienna event possible”.

Jermaine had announced Mary J. Blige and Chris Brown would be among the headliners, but both have since insisted they won't be part of the event.

Brown's spokesperson has said, "Chris is not confirmed to perform or participate in any capacity for this show," and now Blige's people have followed suit - an aide insists the Family Affair singer will be in Italy and not in Austria on the day of the tribute.
