Squirrel Nut Zippers, on a day when the ENTIRE BAND had the flu. Venue was Iron Horse in Northampton MA, which is usually a great place, and SNZ is usually a great band- but I was just cringing the whole time as the obviously worst-affected members, the female vocalist and the bassist, struggled to stand, let alone perform. There were several points when the other vocalist had to take over mid-song. I felt SO bad to watch that!
