Church music links:

For good, singable sacred music, check out Selah Publishing. They publish William Witherup's compositions including his setting of An Irish Blessing - our congregation complains when they don't get to sing it.

MUSICA - the international data base of choral music

Resources for Church Musicians - an Online Workshop - far more useful links than I've been willing to spend the time on thanks to Dr. Rodney C. Murrow

The Royal School of Church Music

GIA

John Bauer - tenor, recording artist, Bethlehem, PA

St Peter's Organ Works - N.P. Mander Ltd, pipe organ builder/restorer in London - St Ignatius Loyola in NYC, and Princeton U Chapel, among others
