The Catholic church of St. Timothy, where Fitz and Penhaligon interview Fr. O'Ryan about Joanne Barnes, was actually on location at St. Vincent de Paul's church in Altrincham, Greater Manchester. The priest was so proud of it that he told the congregation in advance at Mass before the episode was shown, so that we could watch it on TV.
The record on the turntable in the front room at 17 minutes shows the green, white and orange label of Atlantic records.
