Oh my goodness. She comes across as being genuinely grateful for being given the talent she has and for being able to share that talent. She comes across as a warm, caring woman who truly enjoys what she does. She shares many a personal story in between songs.
Oh, she did something a little different. At the beginning of the show, she invited members of the audience to write down and submit questions for her to answer during the course of the show. Once during each of the 2 sets she pulled out a box which held the questions. One of the questions she read during the first set was: would you sign my bra? She said sure. At the break in the second set this rather well endowed woman is invited onto the stage. The woman unbuttons her top, virtually exposes herself and, sure enough, Sarah gets a Sharpie and signs the darn thing. Too funny! Gotta love Berkeley.
Oh, one more thing. She told the audience the last time she was at the Greek, which was about a year earlier, she sat about 10 or so rows from the stage to see Peter Gabriel. I was at that show, seated within beer passing range of her, and I didn't even know it. Her stock went up in my book!
