Matthews Band 2007 Summer Tour, "Sweet Up and Down" returned to full band rotation after being played by Dave & Friends. The third segment, not done at every performance, features Dave Matthews and Trey Anastasio on acoustic guitars, with Matthews playing a DMB song (usually "Everyday") and Anastasio performing a Phish song (usually "Bathtub Gin"), with the two singers singing verses from each other's songs. Sometimes, this segment also included a performance of the Phish song "Waste," which Matthews had previously covered during his solo encore spot at DMB's performances.
