Last video of Jackson rehearsing released along with details of will

In the video Jackson appeared healthy and vital while he rehearsed for his upcoming London comeback shows. Jackson sang "They Don't Care About Us," a song from his "HIStory" album, as he danced along with eight male dancers.

AEG, promoter of Jackson's planned London, England, shows, released the short video of Jackson rehearsing in the arena on June 23.

More information emerged Thursday about how Jackson's estate will be shared, which his will estimated in 2002 as being worth $500 million.

The family trust created by Jackson to receive all of his assets includes his mother, his children and a list of charities, according to a person with direct knowledge of the contents of the trust.

Mother Katherine Jackson's 40 percent share would go to Michael Jackson's three children after her death, the source said.

The children -- ages 7, 11 and 12 -- also will share 40 percent of the estate's assets, and the remaining 20 percent will benefit charities designated by the executors of the will, the source said.
