That fact may help the concert promotion company win the wrongful death lawsuit brought against them by Jackson's mother Katherine and his three children.

AEG Live signed on to promote Michael Jackson's comeback "This Is It" concerts at London's O2 Arena. He was preparing for the shows when he died.

Jackson died on June 25, 2009 and the Los Angeles County coroner said the famed singer died from "acute proposal intoxication" as well as two other drugs, which were allegedly administered by Dr. Conrad Murray.

The Jackson family lawsuit reportedly blames Jackson's death on AEG, claiming the promoters were responsible for Dr. Murray, who was convicted for the involuntary manslaughter of Jackson and is currently serving a prison sentence for the crime.

CNN spoke with an AEG Live lawyer Marvin Putnam for their upcoming documentary "Michael Jackson: The Final Days," which will air this Friday at 10 P.M.

"[Murray] was chosen by Michael Jackson," Putnam told CNN. "He was brought to Los Angeles by Michael Jackson. He had been Michael Jackson's long-time physician and continued in that capacity and was directed by him and could only be fired at will by him."
