He mentions the Jackson 5 being the only group in history to have their first four records go to the top of the charts. He then talks about the legendary Moonwalk at the Motown anniversary show: "It was magic. Michael Jackson went into orbit and never came down."

2:02 - Gordy: "Michael was a master -- a take-no-prisoners showman. I feel that the 'King of Pop' is not big enough for him -- I think he is simply the greatest entertainer that has ever lived." That moving speech nets Gordy a raucous standing ovation.

2:31 - Sharpton tells Michael's children that there wasn't anything strange about their dad, but what he had to deal with was strange.

2:39 - Brooke Shields, a longtime friend of Jackson's, talks about living in the spotlight with Michael. Shields was 13 years old when they met, and she says they had a bond because they both understood what it was like to be famous when they were both so young.

2:41 - Shields says Jackson once tried to teach her the Moonwalk, which she could never nail down.

2:43 - Choking back tears, Shields talks about all the times she got to laugh with Jackson. "He was a lover of life. He cared so deeply for his family and his friends and his fans," she says. She has always thought of him as main character from "The Little Prince," so she reads a passage from the book.

"He epitomized the words of our father, that an individual hasn't started living until he rises above his own personal concerns to the broader concerns of humanity," she says.

2:59 - Texas Congresswoman Sheila Jackson Lee speaks on behalf of the United States Congress and the Congressional Black Caucus. She drives home Jackson's innocence in legal matters, and talks about how Jackson called the world into public service with his music.

3:03 - The Congresswoman tells a story about Jackson visiting a veterans' hospital to talk to soldiers who were injured during the Iraq War. "Michael fought for the tolerance of all people," she says. "Michael fought the good fight."

3:17 - Robinson: "He has made an enormous impact all over the world. I'm glad that I live in this era, that I was able to see the greatest entertainer of all time."

3:24 - Ortega introduces a piece that would have appeared in the "This Is It" shows in London. It's a performance of "We Are the World," featuring a group of singers who would have backed up Jackson during the tour.

3:27 - For the finale of the song, the singers are joined by Jackson's children, Smokey Robinson, Usher, Brooke Shields and a host of others to sing the chorus.

3:29 - Following another standing ovation, everyone stays on stage for a performance of "Heal the World."

3:33 - They're joined by a large chorus of kids, recalling Jackson's iconic Super Bowl performance in 1993.

3:34 - Jermaine returns to the microphone to thank everybody for coming out. He's followed by Marlon, who tells a handful of stories about growing up with Michael (including watching "The Three Stooges" with him). "I have one request, Michael: I would like for you to give our brother Brandon a hug for me."

3:40 - Jackson's daughter Paris takes the microphone and talks about what a great father Michael was, saying "I love him so much" before breaking down in tears. Jermaine says "Thank you and good night" to send everybody home from a moving, emotional ceremony.

3:42 - As the family carries Michael's casket off the stage, "Man in the Mirror" plays over the PA and a single empty spotlight shines down on a microphone, leaving a final poetic reminder that a great artist is no longer with us.

3:44 - Pastor Smith returns one last time, encouraging everybody to follow the message of "Man in the Mirror" to go out and inspire change. "The music of Michael Jackson brings us together around the world," he says. He closes the memorial with a prayer, asking everybody to hold the hand of the person next to them.
