"For the record — nobody knows this because these things don't ever get announced — but we're also working on a new, original show as well," Yorkey shared with Playbill.com. "It's in the really early stages.

"I had the idea for Next to Normal, and I called up Tom, and he said, 'Great.' And, he had the idea for If/Then, and he called me up, and I said, 'Great.' So, it was my turn again… I actually pitched it to him at one of the Tony parties, and he really loved it."

Although Yorkey admitted that the project is in very early stages, it will be about "the power of love and how — in the face of all different kinds of hate — love ultimately can prevail."

The duo, who received the Pulitzer for Next to Normal and a Tony nomination for If/Then, pride themselves in the creation of new musicals. At If/Then's final curtain call, Yorkey told the crowd, "Tom and I wanted to say just a word about courage. It takes tremendous courage to make a new musical happen.… It's a lot easier to go with something tried and true and much harder to take a plunge on something that starts with an idea… and with no idea what it might end up being."

He continued to tell Playbill.com, "With the originals, as you know — [there is] nothing to go on — so we have to sort of make it up out of thin air, and we're starting to do that. It's really exciting. I love doing all of it [including the adaptations of Freaky Friday and Magic Mike], but it's also really exciting to start with nothing and dream that it might someday be something like an If/Then. "So, that's what it's about. You can look us up in eight years, and hopefully we'll have it done!"
