So you can be about your business, and then on it comes again. And this time you're ready, and you've got a wine glass or something. And you put the glass up to the wall, and you can hear through the wall a little bit more of the song - maybe just the middle bit this time. You know, you managed to get in a little bit of the end. And so it goes on until - because you just got to - you really just want to sing it.
