Love the Angus Dei from this mass, getting the phrasing correct was a challenge but well worth the effort.  :)

The Missa brevis Sancti Joannis de Deo, Hob. XXII:7, Novello 8, is a mass in B-flat major by Joseph Haydn.[1] The missa brevis (short mass) was written around 1775 for the order of the Barmherzige Brüder (Brothers Hospitallers) in Eisenstadt, whose patron saint was St. John of God. Scored modestly for soprano, four-part mixed choir, two violins, organ and bass, it is known as the Kleine Orgelsolomesse (Little Organ Mass) due to an extended organ solo in the Benedictus movement.
