Tuning In

All Di, all day

After a year of hype and preparation, the long-awaited “Concert for Diana,” which celebrates what would have been the 46th birthday of the late Princess of Wales, finally takes place on Sunday with an all-star lineup.

While NBC will air the broadcast Sunday evening at 8, VH1 music fans will be able to enjoy the concert through a variety of VH1 platforms, the network said.

The six-hour concert will be broadcast live in its entirety (beginning at 11 a.m.) on VH1, streamed live on VH1.com and simulcast live in HDTV on MHD: Music High-Definition, MTV Network’s high-definition music channel. It will also be telecast on a one-hour delay on VH1 Classic starting at noon and be available for on-demand viewing at VH1.com after the event.

Taking the stage at London’s Wembly Stadium: Fergie, Elton John, Duran Duran, Bryan Ferry, Lily Allen, Kanye West, Rod Stewart, Natasha Bedingfield, Nelly Furtado, P. Diddy, Tom Jones, Take That, Will Young, former Supertramp frontman Roger Hodgson, the Feeling, James Morrison, Orson and Status Quo, the English National Ballet, and Joss Stone.

Aerosmith’s Joe Perry will perform with the legendary Tom Jones.

Anastacia, Josh Groban, Andrea Bocelli, Sarah Brightman, Donny Osmond and Jason Donovan will perform in a special musical medley that Andrew Lloyd Webber put together for the concert.

NBC’s 8 p.m. prime-time special will be hosted by “Today” co-anchor Matt Lauer, who interviewed Diana’s sons, Prince William and Prince Harry, this month on a special edition of “Dateline NBC.” The royal brothers are the masterminds behind the concert, which will feature many of Diana’s favorite artists. Proceeds from the concert will benefit children and AIDS victims, two causes that were dear to her heart, the brothers said.

The special will follow “Dateline NBC’s” encore presentation of Mr. Lauer’s exclusive interview with Prince William and Prince Harry (airing at 7 p.m.).

Fox bringing back ’Dad’

Just ahead of the Fourth of July holiday, Fox has renewed the patriotic animated series “American Dad” for another season, Zap2it.com reports.

Already set on Fox’s Sunday schedule for the 2007-08 season, the renewal will actually carry “American Dad” through to the 2008-09 season, which would be its fourth.

The extended order would bring the show’s overall episode count to 84.

In its second season, the Seth MacFarlane-created comedy averaged just under 7.4 million viewers per week. Less important than its overall viewership, though, is the fact that “American Dad” regularly led its time period among adults 18-34 and teens and controlled a number of key male demographics. For the season, “American Dad” ranked as TV’s No. 5 show among viewers 12-17.

“American Dad” focuses on the misadventures of Stan Smith, a CIA agent with a mixed up family that includes a son, daughter and wife, as well as a martini-swilling alien and a German-speaking goldfish.

Mr. MacFarlane (“Family Guy”) executive produces the series along with fellow co-creators Mike Barker and Matt Weitzman.

Off his game

John Stamos has apologized after making an unusual appearance on the Australian talk show “Mornings With Kerri-Ann.”

According to People.com, the actor, 43, who was Down Under to promote his long-running medical series “ER,” wandered around the set of the morning show, read host Kerri-Anne Kennerley’s lines from the teleprompter and made lewd gestures in front of her.

“John has been traveling extensively for the past few weeks in Greece, Egypt and Tokyo and had a difficult time adjusting to the time difference in Australia, which in turn led to many sleepless nights since his arrival,” the actor’s representative, Lewis Kay, told People magazine. “He acknowledges that his behavior was completely out of character during these interviews and apologizes.”

During a segment with Miss Kennerley, Mr. Stamos took issue with a Sydney Daily Telegraph newspaper claim that he was “bleary-eyed, staggering and slurring,” saying, “[The reporter] took a shot at me in the papers today at being tired.” Mr. Stamos also insulted the writer.

Later in the broadcast, during a discussion about deceased celebrities, Mr. Stamos asked, “Who else died?” and then answered jokingly, “My career after coming to Australia.”

’Wed’s’ Williams on ’M&J’

Hyper funnyman Robin Williams drops by Fox TV’s “The Morning Show With Mike and Juliet” (airing live today at 9 a.m. on Fox5-WTTG) to announce the winner of the show’s “License to Wed” contest — which just happens to be the name of the actor’s new film, arriving in theaters on Wednesday.

The contest measured the compatibility of two competing couples — April and Tony and Mary Elise and John — with the winner chosen by votes cast by viewers.

The winning couple will receive an all-expenses paid week-long stay at Jamaica Sandals Resort.

Platt in ’Nixon,’ ’Nip’

Oliver Platt has signed on to play Bob Zelnick in Working Title and Universal Pictures’ big-screen adaptation of “Frost/Nixon” and has also landed a recurring role on FX’s “Nip/Tuck,” notes the Hollywood Reporter.

Mr. Zelnick was the executive editor of the Frost-Nixon interviews.

Ron Howard is directing “Frost/Nixon,” which Peter Morgan adapted from his hit play. Tim Bevan, Eric Fellner and Brian Grazer are producing the film, which sees Frank Langella and Michael Sheen reprising their Broadway roles as Nixon and Frost, respectively. Kevin Bacon, Sam Rockwell, Toby Jones and Matthew Macfadyen also are on board.

In five episodes of “Nip/Tuck” next season, Mr. Platt — last seen on the small screen in Showtime’s “Huff” — will play Freddy Prune, the producer of a TV show on which Sean McNamara (Dylan Walsh) and Christian Troy (Julian McMahon) serve as consultants.

Mr. Platt, who next appears as George Steinbrenner in the ESPN miniseries “The Bronx Is Burning,” most recently garnered Emmy and Golden Globe nominations for his work in “Huff” and a Tony nomination for his Broadway debut in Conor McPherson’s “Shining City.”
