Here's an excerpt from the story on Broadway Style Guide
For Hughes, the moment she got cast as the Leading Player in Pippin was a defining moment in her career. "I read and sang every single page of that 35-page packet to get it!!" she says. "Then I found out I booked it… as the understudy. I was about to politely turn it down — as I had the fiercest track in Beautiful at the time — when I got a call from casting saying, 'Strike that, reverse it. The team wants you so they've asked Diane [Paulus] to fly in, and if she likes you, you'll take over as the role.' I went in two days later, before my matinee of Beautiful, and did a third and final 35-page audition for the full team and found out between shows that I would be starting rehearsal the next day, as the new Leading Player in Pippin, talking over two weeks later. Yowza!"
