The group shortly reformed as Heart. Pressed by her sister, Nancy joined the band and relocated to West Vancouver. Wilson recalls that "some of the guys" in the band were initially resistant to her joining, and insisted she audition by sitting in periodically. She was given the assignment to work up the introduction to the Yes song "Clap". She learned it, and the next night after playing it with the band at a tavern, was officially made a member of the band.
