U.S. pop star Michael Jackson gestures during a news conference at the O2 Arena in London*Lawyers for concert promoter AEG Live LLC used a testimony from a longtime friend and doctor of Michael Jackson to rest their defense.

As previously reported Jackson’s mother, Katherine Jackson, is currently suing AEG for negligence that she feels contributed to her son’s death.

With the trial reaching its 21st week, jurors are now expected to begin deliberations next week.

Defense attorneys played the videotaped testimony of Jackson’s physician Dr. Allan Metzger.

Jurors listened to Metzger deliver a tribute to the star with Katherine Jackson seated in the courtroom’s front row.

“I saw him as a great guy … a wonderful, generous person,” said Metzger, whose account, given on videotape a year ago, delivered perhaps the most human view of the superstar by any witness.

Metzger talked about Jackson’s desire to end the discontent surrounding his child molestation trial by agreeing to do the ill-fated “This Is It” tour.

“He wanted to redeem Michael Jackson,” said Metzger who visited with the singer at home three months before Jackson died and told of the heart-to-heart talk with him.

“He wanted to redeem his image,” the doctor said. “He felt this was it and he wanted to go out with a flash. He was still terribly hurt about the trial and the accusations. “

After her was acquitted for the molestation trial in 2005, Jackson lived abroad and then returned to begin rehearsing for his “This Is It” tour.

Metzger’s testimony offered contrast to many claims that Jackson was a tortured soul in his last months after being coerced into accepting more dates for the tour than he could handle and ultimately turning to prescription drugs to escape and find rest.

Metzger said the star was energized and scared by the prospect of the shows.

He said their conversation in February 2009 began with “an anxiety call” from Jackson.

“I think he was fearful because this was it and he needed to do a lot of perfectionalizing,” Metzger testified. “He wanted it to be something that had never been done before.”

He recalled that Jackson’s biggest worry was that he wouldn’t be able to sleep when to kicked off his tour in London. That’s when Metzger said he suggested Jackson use a sleep therapist, but the singer refused.

The last meeting Metzger recalled with Jackson, the singer was asking for intravenous sleep medication. He said he refused, telling Jackson it was dangerous and potentially life-threatening.

The doctor also lectured him on nutrition and hydration, noting that Jackson typically dropped seven to eight pounds in every performance.

He said Jackson never mentioned Dr. Conrad Murray or spoke of taking propofol, the drug that killed him. Murray was convicted in 2011 of involuntary manslaughter for giving Jackson an overdose of the drug in June 2009. He is serving a prison term.

AEG Live’s defense has focused heavily on testimony from Jackson’s former physicians, who have detailed their treatments for the superstar. The company denies it hired Murray.

Lawyers for Katherine Jackson were expected to present a brief rebuttal case this week and closing arguments were likely to begin on Monday.
