FYI
SO! At dinner tonight (because he took Susan's comment as a Challenge) Terry transfigured the teapot sitting on his end of the Ravenclaw table into a trombone (the spout was the mouthpiece and the handle became the slide), and then moved over to the Hufflepuff table, yelling HEY SUSAN BONES!
He then proceeded to climb onto the table (avoiding stepping on any food, because sacrilege) and basically enacted this scene (just the singing part of course), except instead he sang as much of the extended version of It's All Coming Back To Me Now by Celine Dion as he could get away with. He only ended up playing a few notes with the tuba, though, because 1. He doesn't know how to play the tuba 2. It was more for show than anything.
