Oh, thank Christ. I first saw this video at a gay bar in New Orleans, and so far my attempts to relocate it with a search for "sexy marching band music video" had been for naught.
While I was delivered the agreed upon ass, I take issue with the promise of brass. I believe saxophone is woodwind, not brass. Had the trumpets been played, then the description would have been apt, but it was not. Consider yourself rebuked, j lzrd / swift idiot.
