This listing derives from a tape fragment that was among the Betty Boards. It should be considered a placeholder, though, because Jerry had probably stayed at the Holiday Inn in Monterey the night before and it seems unlikely that he stopped by to work up MAW with the Dead on his JGB gig in Davis, where he had a room reserved at the Best Western Tennis Club.
