In order to set up the Keynote presentation and have it display as expected, you first need to install some fonts. Because this is a Keynote presentation, this assumes a Mac.
From the fonts/ directory, download and install one copy of the fragile and
wretched fonts. For most modern machines, I believe the tff versions are what
you want.
Extract the zip file, and install using the Font Book app. During the install process, you may see some compatibility warnings for each font. That's expected. Continue installing.
Download beat_the_band.key. Open with Keynote. Confirm that the first slide
looks like this
to see the fonts are installed.
