VIENNA — The King of Pop is to get a royal send-off in Vienna.

Events promoter World Awards Media GmbH confirmed today that members of Michael Jackson's family and a "high-profile lineup of international stars" are planning a tribute concert to be held within a few weeks in the Austrian capital.

Organizers said they'll announce the date soon, but the venue is set: an outdoor stage shaped like a crown at the sculpted and sprawling grounds of Vienna's former imperial Schoenbrunn Palace.

Tickets will go on sale Aug. 20, World Awards Media said on its Web site.

"For one incredible night Michael Jackson's unforgettable music will be brought to life again," it said. "Some of the world's leading artists will perform Michael's greatest hits live in Vienna in front of one of the most fascinating historical sites in Europe and celebrate the life of the 'King of Pop.'"

Organizers said Jermaine Jackson and other family members "will lead a high-profile lineup of international stars on stage to celebrate the life of his brother and perform some of Michael's unforgettable songs."

They would not confirm Austrian media reports that the outdoor tribute may include U2, Madonna, Lionel Richie and Whitney Houston.

There were conflicting reports today about the date. Some said the tribute still might be held Aug. 29, which would have been Jackson's 51st birthday; others said it will be staged in mid-September because organizers need more time to plan.

Jackson died June 25 in Los Angeles.
