The toll it took on her physically was apparently a lot not to mention the pressure of an entire show resting on you. I think she'd have done more concert work, but I don't think she'd have come back as, say, Mame in 2003 or anything."
I agree. Her return to Broadway in 1996 with Victor/Victoria was after a very long hiatus; granted, she had a very active film career during that time. Her role in Victor/Victoria was based on a film role she created 15 years earlier, so that film role served as the impetus for her to come back to the stage. As you said, the role took a toll on her. In addition, she was bitter because come Tony time, she was the only nominee from her show, which she publicly denounced as an "egregious" oversight. In a show of solidarity with her fellow artists and creators, she declined the nomination. Even though her name officially remained on the ballot, the Tony for Best Performance by a Lead Actress in a Musical went to Donna Murphy for the The King and I. If Andrews hadn't declined the nomination, I think she would have pulled off a win if only for sentimental reasons. I remember seeing the show and thinking it was pleasant, but not great. I enjoyed the opening number, "Paris by Night," but the rest of the show as just okay. Given the dynamics surrounding the Tony nomination and the stress of carrying a Broadway show, I don't think she was really interested in taking on additional roles that required 8 shows a week, even if she only performed 7 shows like Midler did in Dolly!
