It's a little too early for an April Fool's joke, and the press release seems a little too earnest to be untrue, so let's report it straight: Green Day is bringing American Idiot to the stage. (The "thee-u-tah," if you will.)
It's too early in the week for any more jokes than that one, so I'll just copy-paste a quote from the press release and point you to an article in Variety instead.
Oh, also: New Green Day album May 15.
"We are really excited to be working with Michael Mayer on this project," says Green Day's frontman Billie Joe Armstrong. "We'd been thinking of bringing American Idiot to the stage, but knew we needed to find the right partners. After meeting with Michael to discuss the possibility, he invited us to see Spring Awakening. We were so impressed with that production, as well as his vision for American Idiot, that we knew we'd found the perfect collaborator. Plus, doing it in our hometown at Berkeley Rep was an obvious bonus. They're an amazing theatre group, very adventurous, and their willingness to take chances is in keeping with the spirit of the album. The end result will be terrific, and we're really proud."
