After far more time than I probably should have spent, I have completed the programme for solemn Matins on Christmas Night. I now have the go-ahead from my parish priest to have the choir sing it before Midnight Mass. Thanks to Steven van Roode for his help with my queries.

The breakdown is as follows:
- All English texts from the UK/Aus translation of the LOTH, via Universalis
- Invitatory Antiphon, Venite and Hymn from the Liber Hymnarius
- Other antiphons taken from Gregobase
- Psalms and canticles sung to Anglican chant (specifically chosen to complement the plainchant antiphons)
- Responsories included in two different formats:
--- chant from Liber Hymnarius
--- fairly simple Renaissance polyphonic versions
- Hour "extended" as per GILH with OT canticles and Gospel
- Te Deum to simple tone as found in Liber Hymnarius

I'm yet to finalise a congregational booklet, but I can post it here when it is finished.
