Here is a link which also has a review I wrote as Simul.
Recently, at a music workshop at Concordia, someone had brought back the Posaunenchor book (brass band book) to go with the hymnal. It has the same kind of cover and is obviously co-ordinated with the hymn book. I have not yet tried to locate it on Amazon.
Just because it's spring and I feel like it I will add a of pictures of this trip.
