St John's College, Cambridge are not unique in making their sung services available as web-casts, but I have yet to find a college who makes it so easily accessible (and easy to skip to different parts of the service). Here the Gentlemen of the Choir beautifully sing the Byrd three part Mass, and Durufle's Ubi Caritas.
Of particular importance, we hear the polyphonic Credo and Sanctus - what a shame these are "forbidden" (or as good as) in the Roman Rite.
