This is getting rediculous. Listen to the record, man. While her voice drops down on the 'does' part, the backing track stays at the same speed and tone. She drops her voice down a considerable amount, although not as significant as the formentioned part, at other parts during the song...it's just how the song is sung, but there's no use in talking to a wall.
You totally scared off a guy that was interested in it by claiming that there is a "fault" in the record...you owe me a George Carrow record now
