I had no idea how difficult Sondheim's music would be. All through the rehearsals, I kept flubbing. There were so many tempo changes. I could never get through the opening number without any mistakes. One day, I went up to Hal Prince and offered to leave the show. He laughed it off. He said, 'Don't be silly. That's why we have tryouts.'
