Organizers say the outdoor tribute concert for Michael Jackson scheduled later this month in Vienna will now be postponed and held in London.

World Tribute Productions organizer, George Kindel, said Friday the concert will be held next June around the one year anniversary of the pop star's death.

Kindel said the tribute will be held in London's Wembley Stadium.  He also said those people who bought tickets to the Vienna concert will be refunded.  

Earlier this week, organizers and Jackson's brother, Jermaine Jackson, announced the Vienna concert would feature popular artists including Mary J. Blige, Chris Brown, and Natalie Cole.  

Jackson died June 25 at the age of 50 from a lethal combination of drugs that included the powerful anesthetic propofol.

The Los Angeles coroner's office has ruled his death a homicide.
