The curtain is slowly rising on Michael Jackson's last show.

As in Jackson's life, Tuesday's public memorial at the downtown Staples Center includes the spectacle surrounding the show — legal drama, screaming fans, star power, live worldwide broadcast, unsavory accusations, even a parade of elephants — all adding up to what could be the biggest celebrity send-off of all time.

On the eve of the memorial, activity was spotted late Monday at the Forest Lawn Cemetery involving the Jackson family. The cemetery is the location where relatives were expected to hold a private funeral.

La Toya Jackson, wearing sunglasses and a wide-brimmed hat, was seen being driven away from the cemetery. KCAL-TV showed helicopter footage of a hearse backing up to the Hall of Liberty — a circular building at the cemetery that contains a 1,200-seat auditorium — to deliver a casket.

A few hours later, the casket was reloaded into the hearse and delivered to another nearby building, this time covered in a blue cloth.

It wasn't immediately known if the casket would be at the memorial service. Jackson family spokesman Ken Sunshine said Tuesday on NBC's "Today" show that the family would not comment on it.

More than 1.6 million people registered for free tickets to Jackson's downtown memorial. A total of 8,750 people were chosen to receive two tickets each.

"I got the golden ticket!" one fan screamed out of his car window in a Willy Wonka moment as he drove out of the parking lot.

The family announced that participants will include Stevie Wonder, Mariah Carey, Usher, Lionel Richie, Kobe Bryant, Jennifer Hudson, John Mayer and Martin Luther King III. Sunshine told ABC that Queen Latifah also will be performing.

Los Angeles Police Chief William Bratton said Tuesday on CBS' "The Early Show" the department would have more officers on the streets of downtown for the memorial service than it had for last month's Lakers victory parade.

Bratton said officers "really just do not know how may people will actually show up" and that officers "are prepared for anything."

"Crowds have not materialized so far, and that was the one unknown," Bratton told KTLA-TV early Tuesday morning. "We ramped up very significantly in anticipation of very large crowds, but cost-saving wise we'll try to ramp down very quickly if those crowds don't materialize."

A few dozen people, some wearing the gold wristband that will allow them into the memorial service, gathered early Tuesday at the perimeter set up outside the Staples Center.

"They're touching us and saying, 'Can you bring the love in for us?'" said Mishelle Van, 37, who said she drove from Hesperia to spend the early morning hours meeting other Jackson fans.

The legal maneuvering that marked Jackson's extraordinary and troubled life also continued Monday, with his mother losing a bid to control his enormous but tangled estate. And in one of the few reminders of Jackson's darkest hours, a New York congressman branded Jackson a "pervert" undeserving of so much attention.

British Airways reported a surge of bookings as soon as the memorial arrangements were announced. Virgin's trans-Atlantic flights to San Francisco, Las Vegas and Los Angeles were all packed with fans and VIPs, spokesman Paul Charles said.

About 50 theaters across the country, from Los Angeles to Topeka, Kan., to Washington, D.C., were planning to broadcast the memorial live, for free.
