Kids Say the Darnedest Things About Their Marching Music

A high schooler who had a lesson today noted that "they gave us a copy of this thing called the Woodwind Feature. I think it's supposed to be an oboe and euphonium duet." Never mind the fact that a euphonium isn't a woodwind; has anyone ever heard of a duet between those two instruments...on the field? I'm thinking the kid misheard something. (On an only slightly related note, I'm amused that my new[ish] computer's spell check doesn't recognize "euphonium" as a word.)
