Jon was in his element, telling stories, relaxed, joking around, and sounding just awesome vocally. I had heard that it was slightly rough at first, but the last 3 or 4 songs I heard were just spot-on and sounding real good -- high notes being hit with accuracy and feeling. A guy named Keith accompanied Jon (with acoustic guitar in hand) on oboe, making for a nice segue for my personal club hopping experience. I was surprised to hear him do "24" from his Switchfoot catalog. He explained that he'd written it the day before he turned 25.

Keith plays oboe...? Hehe... I thought that thing was called a "cello" ...?
