Moore suggested the Church of the Holy Trinity in Toronto for its natural reverb. To better persuade the officials of the historic church, the band claimed to be the Timmins Family Singers and said they were recording a Christmas special for radio. The session began on the morning of November 27, 1987. The group first recorded the songs with the fewest instruments and then the songs with gradually more complex arrangements. In this way, Moore and the band were able to solve acoustic problems one by one. To better balance Margo Timmins' vocals against the electric guitars and drums, she was recorded through a PA system that had been left behind by a previous group. By making subtle changes in volume and placement relative to the microphone over six hours, Moore and the band had finally reached the distinctive sound of the album by the time the last of the guest musicians arrived at the church.
