My brother was born when I was 2 and wouldn't slepp through the night, so we had to be extremely quiet if he ever did manage to nod off. So, when I heard "away in a manger" I honestly believed, for a good few years, the the lyrics were "the kettle is boiling, the baby awakes..." as opposed to the cattle are lowing etc! We had an old fashioned whistling kettle at the time, which may have helped me on the way to that belief!
