When I played Pomp and Circumstance for high school and Harvard Business School graduations (for some reason our HS band had a standing gig to play the HBS graduation), it was kind of a meditative focus, but not really any enthusiasm. It's not like you need enthusiasm for that melody. It became kind of trance-like, like good folk dancing.

Or, I sang the reindeer version in my head (my reindeer is puuuur-ple, your reindeer is broooown; my reindeer flies siiiiide ways, yoooours flies up-side doooown...)
