Colorful banners drape the wagon and, as it approaches, you hear music emanating from within. It rolls to a stop and instantly shifts, transforming and reshaping seemingly with magic. A stage unfolds from one side, with a canopy rising above it. The chimney spouts smoke of a dozen colors, tingeing the air with strange and exotic smells. The door bursts open, releasing a flock of rainbow-colored birds whose feathers shine in the light glowing over the stage. The music now booms outward—blaring horns, crashing cymbals, and thunderous drums.
