From Chelan, Washington: “CCWatershed is a God-sent resource that I can’t function without!

I created this organ accompaniment booklet for organists who will accompany Vespers on Pentecost Sunday. Feel free to download it; it might give you some ideas or inspiration. Be warned: It looks pretty sloppy. (The organist is the only one who sees it.)

From a reader: “I wasn’t looking for it. But, I stumbled across your hand-dandy arrangement of Pachelbel’s Canon. Jeff, this is the greatest thing since sliced bread!
