This is a credits sequence found with some Colonel Bleep episode encodes. It is unclear whether it came from the actual show or was originally created for a VHS tape from the 1980s, but it is in the public domain for the following reasons:
<ul><li>only public domain images and sounds are used in it (from the show)</li>
<li>the words in the credits are public domain because they state simple facts, and the font is not creative enough to be copyrighted</li></ul>
Lawyers wouldn't care anyway though.
