Peter Hollens could make any arrangement sound good, but Tom Anderson's arrangement of "Loch Lomond" is very nicely done. As a pianist and arranger, I love being able to study the score and being able to listen to a performance as I read the score. What better way to learn than to listen to excellent music and really think about it. I'm glad the arrangement is available, and if you need music this will be very useful. If you're ultra finicky about notation, you'll see a few minor infelicities (some words that are squeezed and some non-standard use of rests), but there is nothing that prevents a clear understanding of the music.
