My son's high school marching band recently marched down Main Street and I got to wondering who the announcer is ("Ladies and Gentlemen, Boys and Girls...lets' give them a warm welcome"). I can't seem to find a definitive answer on the web or in MiceChat (not to say there isn't an answer, I just can't find it!).
He's also the voice who announced the fireworks were cancelled due to wind conditions.
