As a favor to Margherita—who had spent a substantial amount of money to keep the band running—Farrar agreed to a final tour with Uncle Tupelo in North America. Tweedy and Farrar again engaged in a shouting match two weeks into the tour, due to Farrar's refusal to sing harmony on any of Tweedy's songs. The band made its first appearance on national television during the tour when they were featured on Late Night with Conan O'Brien.
