Several tracks from The Band's 1968 classic album "Music From Big Pink" contain parts listed as a "high school horn". This is none other than an old-school "American baritone horn" that was common in years past! Most of the parts are just long tones to pad the sound a bit, but "Chest Fever" actually has this goofy break in the middle that is a trio between the baritone, violin, and saxophone. It sounds like a really out-of-tune salvation army band! Give it a listen.
