In Kander & Ebb's book 'coloured lights' they explain that several women were approached for the role:
1. Angela Lansbury, who of course dropped out (there is a demo recording of her singing Love and Love alone on YouTube, which is fantastic. I can easily imagine her facial expressions)
2. Glenn Close was then approach who 'turned us down'
3. Judy Dench was approached but wasn't available
4. Shirley MacLaine was 'interested at first' but then had a conflict
However, ultimately John Kander believes that there are 3 people who he thought were perfect for the part: "One was Angie, one was Judi Dench, and one was Chita. I still feel that way. As far as I'm concerned, we got one of my top three performers and nobody will ever be better in this part than Chita. She gives the performance of a lifetime".
I personally think the part is wonderful and I am excited that it will provide Donna Murphy, Patti LuPone or Bernadette Peters something to play in the future.
Give me claws and a hunch, just away from this bunch.
