Hey, I'm for a certain amount of ecumenism in music, but there's no need for slumming. Proulx si', Haugen no'!
For those of you who don't know, Richard Proulx is a composer and arranger who has written some great stuff, including an arrangement of "O God Beyond All Praising" based on some hymn tune that I can't recall right now because it's 100 degrees in Washington DC. In any case, I highly recommend his work. GIA has published a bunch.
