Conan O'Brien, 'Weird Al' Yankovic & more will bring Springfield to Hollywood.

"Weird Al" Yankovic, Conan O'Brien and Beverly D'Angelo are among the voices of Simpsons characters who will perform songs they sang on the long-running animated series at the Hollywood Bowl this weekend.

Hank Azaria, the voice of Moe and Chief Wiggum, will host the world premiere event The Simpsons Take the Bowl that plays Sept. 12, 13 and 14 and features appearances by Jon Lovitz, the Gay Men's Chorus of Los Angeles, Vaud and the Villains, Simpsons creator Matt Groening, the voices of Bart (Nancy Cartwright) and Lisa (Yeardley Smith) and Kipp Lennon, the singing voice of Michael Jackson. Thomas Wilkins will conduct the Hollywood Bowl Orchestra.

"There will be a big tribute to Danny Elfman's theme, lots of Alf Clausen's scores, a medley of different opening credits," says Al Jean, a producer of more than 450 episodes of The Simpsons. "For me -- and I think for longtime fans -- this will be really meaningful."

O'Brien will perform the song he wrote for the show, "The Monorail Song"; Weird Al, who will coincidentally be included in a new line of Simpsons dolls, has expanded one of the songs he wrote for the show; D'Angelo will tackle songs she did in The Simpsons Movie; and Lovitz will perform "Stop the Planet of the Apes, I Want to Get Off."

The concert event, which will feature unreleased clips, will not feature any musical celebrity elements.

"We didn't want to say 'here's a clip of the Who -- but the Who's not here,'" says Jean. "We didn't want to do anything that wasn't live and immediate for the audience."

The Simpsons, which premieres its 26th season on Sept. 28, will continue to weave musical personalities into its show this year. Pharrell Williams will have a cameo, and members of the Lonely Island have written music based on a true story that occurred in Calgary, Alberta, where the city learned that their town anthem was actually sold to a bunch of different cities.
