A planned September tribute concert in Vienna for the late Michael Jackson is generating a frenzy of fan excitement, despite the fact that the line up of artists and exact logistics have yet to be announced, according to MTV. The show is being co-organized by Jermaine Jackson, and demand for tickets apparently temporarily crashed the servers hosting the official Web site. Tickets were scheduled to go on sale today, August 20, and the show is slated for September 26 at the Schoenbrunn Palace in Vienna, Austria.
