76. The American Astronaut - Hey Boy
This is the first real musical number in the film, and it was the moment I pretty much fell in love with the movie. That may say something about my mental state. In any case, after I saw The American Astronaut for the first song, I got this song stuck in my head, and it took repeated watchings to get it back out.
In any case, the number does do a lot to set the mood of the film. Everything is just slightly off-kilter, except when it's severely off-kilter. And this number, combined with the stand-up comedy and dance contest number which follows (and is much "bigger") give you something of a sense of what the rules are in the film.
