SATB/piano - also can be sung a cappella - traditional - arr. Keith Murphy and Peter Amidon
You get pdfs of the piano/SATB score and the vocal score, and mp3 of the recording, and rehearsal track mp3s of each of the four vocal parts. Performed here by the Starry Mountain Singers (with Cora Kelly and Peter & Mary Alice Amidon). Earlier in the year Peter heard Keith lead this song with some young fiddlers and singers, Keith accompanying them on piano. Peter was struck by Keith's harmonization and did this SATB arrangement based on Keith's harmonies, and later transcribed Keith's piano part from the Last Night Concert performance. You get both the SATB/piano score and the vocal score. This also works fine a cappella. Here are some other interpretations of this classic:
