Details of Michael Jackson's public memorial remained under wraps on Sunday as Los Angeles police braced for a huge crowd of fans expected to turn out and again warned those without tickets to stay away.

About 1.6 million people registered to be one of 17,500 people inside the memorial at the Staples Center sports arena in downtown Los Angeles Tuesday or to watch it on large video screens at a nearby theater.

Fans who won tickets were to be told by e-mail on Sunday. The company sponsoring the event will pick 8,750 names from a list of online lottery entrants each winner will receive two tickets.

A family spokesman declined to give details of the event, such as who might eulogize Jackson or which of the King of Pop's celebrity friends may perform. He did not offer specifics of a separate, private family funeral, and police told Reuters they did not have any information about the private ceremony, either.
