This just makes me laugh!!!
As a former marching band person myself, I currently don't require a pause in music to stumble a bit. MS takes care of that for me. Once, I walked off the edge of a curb, right on top of the air, and found myself lying flat on my front - arms outstretched. But I'm sure that I looked as graceful as swan doing it, especially since I didn't even spill my doggie-bag in the process. Hehe.
