JERMAINE JACKSON’s tribute concert for his late brother MICHAEL has been cancelled - because not enough big-name stars signed up to perform.

The show was scheduled to take place in Vienna, Austria on 26 September (09), but has now been put back to next year (10) and moved to London after organisers failed to secure enough acts in time.

In a series of press conferences this week (begs07Sep09), Jermaine appeared to confirm a string of stars including Mary J. Blige, Chris Brown and Natalie Cole had signed on to perform at the concert.

Just a day later, Brown’s reps denied he was involved in the gig, while Blige revealed she would struggle to make the show because she had prior commitments in Italy.

Cole also called time on her appearance - her spokesperson confirmed she was scheduled to be at an event in Memphis, Tennessee with the Dalai Lama on the day of the King Of Pop extravaganza.

Now, just two weeks before the show was due to take place, organisers have axed it. Instead, the tribute to the Thriller icon will take place in the U.K. capital in early 2010.

The show’s producer Georg Kindel says, “Maybe we underestimated these (scheduling) issues. It was very difficult to put up the show, which normally needs six months.

“Due to this fact, we decided to reschedule the event for the first half of June 2010, but not in Vienna, in London.”
