This is heartbreaking. I'm sure the lights will be dimmed for her.
Several years ago, I was fortunate enough to see her live in a small, intimate cabaret setting in San Francisco. It was supposed to be Elaine Stritch, but Stritch cancelled due to her health, and the venue was able to get Barbara Cook on somewhat short notice. I was a bit disappointed at first because, being the silly youth that I was, I wasn't really aware of Cook's talents. But boy did I wise up. I sat in the front row of tables, and could not stop beaming through the whole show. She needed heavy assistance to get up to the stage, because she was no longer very mobile. She sat down through the whole performance, and left in a wheelchair. But THAT VOICE had not diminished in the slightest. It was still as gorgeous as ever. Plus, she was still sharp as a tack. It was a pleasant surprise to learn that this grand, elegant lady of the Golden Age of musical theatre, actual swore like a sailor! What potty mouth!
After the show, she sat in her wheelchair behind a table in the lobby, and spent at least an hour chatting with her fans. I was one of the first to speak to her, and she said "you looked like you were enjoying the show!" and I said "I certainly did!" I then spoke with her for a little longer, before I asked her for a photo. She said yes, enthusiastically, and I went behind the table for the photo. Right before the photo was taken I felt her grab my hand and say "hold my hand for the photo!" She insisted on holding the hand of every fan that she took a photo with that night. One girl came in with the score of Candide (she was preparing to play the role), and the two of them spent about 15 minutes meticulously going through the score, Cook giving advice along the way.
That evening remains a treasured memory. She will be sorely missed.
