The "dirty night clowns" can also be generalized to refer to any and all child molesters. The chorus ("I can't clear the leaves from here; they're too far under the brush this year") refers to how the "dirty night clowns" have "trees to shade the moves that they made." The "fallout" of those trees are leaves that pile up under the "brush" (another word for "bushes"). I think this refers to the psychological damage of such abuse and the difficulty of facing and finally overcoming it.
