Jackson's Agent Fires Back At Failed Concert Promoter

Promoter Roy Isaac alleges Jackson agreed to play a tribute gig for his late brother Michael in the U.S. state following the superstar's death last year (09).

Isaac claims Jackson kept the money despite the gig never coming to fruition, and threatened the star with legal action if the cash was not paid back within 30 days.

Jackson's rep subsequently told TMZ.com it was his client's booking agent who had the money, and that Jackson received none of it.

Now, the singer's agent Peter Seitz has fired back at Isaac, insisting he failed to properly plan the event. He tells TMZ.com if the show is not organised for another date, Isaac owes Jackson money for wasting his time promoting the tribute gig.

Seitz also tells the website Isaacs should "apologize and retract the story".
