We just got this march in our folders last week. It's a very good march with nice counter melodies for the euphonium. One of the few that I can remember that repeats back to the beginning... rather than the first strain. It's a circus march, so is taken pretty fast... faster than what I've found on YouTube so far.
Here's a link to listen to an mp3 file:
