She's a treasure. Every time I've seen her live, she's been great. First time was touring Life on a String, then the show right after 9/11 when she did effectively the same set as on the live album, Live in New York aka Live at Town Hall, and then once at the Birchmere where she had technical difficulties and she was STILL great.
I actually just quoted the grits section of New Jersey Turnpike to a group of people from the South that were arguing for and against grits.
