Bono, The Edge to work on 'Spider-Man' songs

U2's Bono and The Edge will spend this week at previews of "Spider-Man: Turn Off the Dark" working on the songs of the Broadway musical that Bono calls "a pop-art opera."

"If you go to the theater, transformation must take place," Bono told Carson Daly on NBC's New Year's Eve coverage. "People fly behind you when you're sitting in the seats. There's fight sequences happening in the roof. Things happen that you've never seen in the theater before."

Though the $65-million "Spider-Man," the most expensive Broadway musical ever, has faced numerous delays, production issues and cast injuries, the show's star, Reeve Carney, said the cast is ready and looking forward to performing for the U2 pair.

"Singing in front of them sort of lights the fire underneath me that I need to perform," Carney said on the NBC broadcast. "It makes it much easier to perform. I bring my 'A' game, I guess."

The Edge, who co-wrote the show's music with Bono, said "Spider-Man" will break new ground.

"We don't know what to call it because it is rock and roll, it is musical theater, it is circus, it is opera - everything put together," he said. "If you're not going to do something revolutionary, why bother?"

The Edge said Spider-Man comic book creator Stan Lee has already given the show his approval, adding, "The minute he saw the sets, he said, 'I'm in, I'm in, this is amazing.' "
