Trivia:
- The psychiatrist scenes, although being the shortest, probably took the longest to film.

- James Byrne doesn't really hate Christmas.
- Chris Malone was never considered to record the music for Santa's Psychiatrist, after an incident while recording the score for 'Norman's Book'.

- The first Psychiatrist scene was originally double in length, but a lot had to be cut due to bad sound recording on the evening.
- The Smurf costume cost £20 to hire from a local costume supplier.
- Mark Sheppard actually sang 'Do They Know It's Christmas? ' live in the church, in front of a vicar.
