I remember a few years ago I tried to transpose a trumpet version of this song (with all melodies included) to bass clef euphonium (that's what I play) and it came out pretty good. Sadly I have lost that music but I would love to try to transpose it again just for the fun of it
Decent harmonies, but as a brass player, this would be a nightmare to play. For it to be somewhat successful, you would need at least two people per part, or assemble the world's greatest circular breathers. This would definitely be more suitable arranged for brass ensemble instead of quintet
