Had been thinking about recording our efforts each Sunday, but I see someone has already done this;

Note this an older style of compline, but much of it would be the same for Sundays.

Note the Hymn melody and other parts will change with the seasons / feasts.

A full Compline book Latin / German can be found here;

Another recording can be found here not that I can get it to play on my computer;

Sorry if this is a bit late.

If the recordings I put up on the Orkney Chant blog are of any use at all, I'm glad. I made them precisely to help my own schola get familiar with the sound of Compline. The reasons we follow the Nidaros use are complicated, and probably don't make much sense outside my head ... but I wanted people to learn something that would be transferable if they ever happened to sing Compline in the older form (or even in the newer form in Latin, e.g. using Fr Weber's book), so wherever possible I've followed the music of the Liber Usualis rather than digging around for obscure sources of medieval Scandinavian chant.

There's a recording of the whole of Compline (according to the Liber) here:
