Michael Jackson Drug-Induced Rambling: "I Had No Childhood"

Michael Jackson wanted to dedicate his "This Is It" concerts to his children -- and in a heartbreaking conversation Dr. Conrad Murray recorded weeks before the singer died, MJ claims, "I love them because I didn't have a childhood."

You can hear MJ's voice in the recording -- slurred, incoherent -- explaining how he wanted to outdo The Beatles and Elvis with his final concerts, and go down in history as the greatest entertainer who ever lived.

Michael becomes extremely emotional while speaking about his children -- claiming, "I had no childhood. I feel their pain. I feel their hurt."

Murray recorded the conversation on his iPhone on Sunday May 10th, 2009 at 9:05 AM. It's unclear why -- but according to prosecutors, it documents MJ under the influence of "unknown agents." It also shows Murray was familiar with Michael in altered states of mind.

At one point in the clip, Murray asks Michael if he's okay -- and Michael responds, "I am asleep."

The recording -- a clip of which Prosecutor David Walgren played during his opening statement -- was uncovered by investigators after they seized Murray's device.
