The September 26 show is being organised by MJ"s elder brother Jermaine Jackson and it is believed he has been trying to rope in many stars including Whitney Houston, John Mayer and Lionel Richie for the show. Over a million MJ fans have already requested for tickets online.
World Awards Media, which is jointly organising the concert with Jermaine, has released a hand-signed letter from Katherine Jackson, reports the Daily Star.
Katherine writes: "An event of this dimension not only keeps Michael's spirit alive, more than that: It gives millions of fans the opportunity to experience his music and celebrate the life of my son. I am sure Michael would love it. I fully support Jermaine's endeavours to spread Michael's important message of making a better world for us all... (I am) overwhelmed by the worldwide love and support that my beloved son Michael has received over the past month."
The performers for the concert are expected to be named by the end of this month. Jackson, 50, had died on June 25 after suffering a cardiac arrest.
