Oy, honestly I think they have been playing that marching music at CP since the 80's, the 1880's that is.
At CP at least, music was made for DJ booth, not for the midway. I like to the screams of people, the rush of rides, and the sweetest sound of all, the rollback dogs. The last thing I want to hear is "Yankee doodle dandy" on what sounds like my car stereo coming from the lot.
When they do play "real" music, it usually in the form of Smokey Robinson's "Tears of a Clown." I heard that so many times last year it made me cry,
