There will be 11,000 tickets distributed to the general public.

PR firm Sunshine Sachs & Associates, hired to speak on behalf of the family, will hold a press briefing Friday morning at 10 a.m. PT to announce details on how the public can register for tickets.

In a press conference Thursday, the producer of Michael Jackson's scheduled This Is It Tour said they have 100 hours of high definition Jackson video footage for use in a documentary film and/or live albums.

Randy Phillips, CEO of AEG Live, also said the company is considering producing a Michael Jackson tribute concert at London's O2 Arena, the venue in which Jackson was scheduled to perform.

"There are all kinds of things that we've been talking about, potentially a motion picture. A pay-per-view tribute," Phillips said. "This production was breathtaking. Remember, Michael didn't do anything small. Our production budget was well in excess of $24 or $25 million dollars, which for an arena show is unheard of. It's breathtaking. It's technology people hadn't seen before."

Phillips said AEG doesn't want to be a "burden to the (Jackson) estate" and hopes to recoup the money lost from the tour cancellation via the tribute show, movie or album.

Also Thursday, a judge delayed a guardianship hearing for Jackson's children scheduled for Monday at the request of ex-wife Debbie Rowe's attorneys. The hearing has been rescheduled for July 13.

Rowe's attorney said Rowe is still deciding whether or not she will seek custody of the children she had with Jackson, the Associated Press reports. She is the mother of Michael Jr., 12, and Paris, 11. Jackson's youngest child, Prince Michael, 7, was born to an anonymous surrogate.

Earlier Thursday, Jackson's older brother Jermaine spoke out in an interview with the Today show, saying that he would be "hurt" if toxicology results indicated that his brother's death was drug-related.

"In this business, the pressures and things that you go through, you never know what one turns to," he said. "I don't know about these things, because I hate anything with drugs."

Jackson's 7-year-old will was filed in an L.A. court Wednesday, specifying that his estate would go the Michael Jackson Family Trust and that Katherine Jackson would be the beneficiary as well as the guardian of his three children.

Also Wednesday, the Los Angeles Police Department asked the Drug Enforcement Administration to aid in the investigation in to Jackson's death.

"We cannot comment about our involvement in the investigation of the death of Michael Jackson," DEA spokesman Garrison Courtney said. "We routinely assist other law enforcement organizations on cases involving the diversion of prescription drugs. We often get involved at the request of other law enforcement agencies."
