Is she still funny and self-effacing?
When I saw her maybe 20 years ago, she started to pontificate about something by saying, "In my humble opinion....."
Then she stopped and said, "Who am I kidding? I've never had a humble opinion in my life!"

Her singing may not have been quite as good as it was when she was 20, but she was still a darn good singer - and she had a delightful, intimate relationship with the audience.

Indigo Girls and Mary Chapin Carpenter are also good, but Joan Baez was absolutely delightful when I saw her.
