The album "Bad Animals" (1987) was preceded by the single "Alone"; it became the band's second number-one hit, and the second-biggest single for the year. This gave them something they had not had with the "Heart" album: a number-one single before the tour started or the album was released. "We were following on success, not building to it," Wilson recalled. The Bad Animals tour was to start in May 1987 in Europe, and all the dates were sellouts, including three dates at Wembley Arena. During the tour, Ann began to have moments of panic and stage fright. Nancy would have to step forward and play an unscheduled guitar solo, or other ploys, to buy time for Ann to compose herself. Work began on the following album, "Brigade", in 1989.
