THE tribute concert for Michael Jackson, set to take place in Vienna this month, has been rescheduled for London in June 2010. Numerous stars were just not able to change their schedules to make a live appearance at the Vienna event possible, said The event promoter in Vienna said that too many top performers had scheduling conflicts. Maybe we underestimated these issues, promoter Georg Kindel was quoted as saying by the Associated Press. The event had been due to take place on 26 September at Viennas Schoenbrunn castle. Earlier, representatives for Mary J Blige, Chris Brown and Natalie Cole said none of the three would be at the concert, as previously announced. BBC The tribute concert originally planned for September 26, 2009 in Vienna 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. Many artists and performers who I have spoken to personally told me that it would be a great honor to be part of this memorial concert for my late brother - an artist who influenced the music world like virtually no other. However, due to the short time frame it was not possible for many of them to change their schedule so that they could be on stage in Vienna on September 26, therefore we decided, after careful consideration, to change the date of the tribute concert to June 2010 - just a few weeks before the first anniversary of his untimely death, is how Jermaine Jackson explained the decision. Further he stated: 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 Michaels high standards, but numerous stars were just not able to change their schedules to make a live appearance at the Vienna event possible.
