It is scheduled for Oct. 8 in Cardiff, Wales. Christina Aguilera, Smokey Robinson and Cee Lo Green are among the show's announced performers. The show is not affiliated with Jackson's estate, but Jackson's mother, Katherine, and other Jackson family members are scheduled to attend.

Organizers had to rescind an offer to the band Kiss last month after fans and Jackson's estate noted that singer-bassist Gene Simmons had harshly criticized the pop singer over the years.
