I saw the show Thursday night, and Andrea was on for Cristin then. Interestingly, that was the night of the Letterman performance which aired at 12:30am later that evening which had Cristin on it. I know that the Letterman show often tapes around 5:30-6:30 about 6 hours before the telecasts...so, did she tape that and then take her absence? Or was it taped on a different day?
