While shepherds watched - CD - CDH55325 - Hyperion Records
It's a slightly tarted up version of the sort of music that used to be sung in churches and chapels in the Georgian era. If you scroll down to the sleeve notes they are very informative. There were several hundred tunes to While Shepherds Watched, listen to track 9 where the tune is the original of On Ilkley Moor Baht 'At and track 15, known asOld Fosters.
I used to be in a costumed choir that performed this sort of music. In this picture I'm the one in the bonnet between the cello and the drum.
