The St Andrew's Mass is a setting of the ordinary mass for two choirs: a full SATB choir which sings in Latin, and a quartet or semichorus which sings in Scottish Gaelic. There is an incredibly rich singing tradition in the Gaelic language, including highly ornamented responsorial psalm singing still practiced by Presbyterian congregations in the Outer Hebridies, and mouth music or nonsensical, highly rhythmic folk songs intended to accompany dances. However, generally speaking these traditions are un-notated. Hear, see, and buy it on MusicSpoke. http://musicspoke.com/downloads/st-andrews-mass
