You can visit http://freepd.com to see what it has to offer for yourself. But it is public domain audio file in entirety. I archived it for personal use, so I've uploaded it here since it took 2 days to archive it which it will not to download it.
(The same as the website archive except all HTML and other files aside from the audio have been removed. So it is nothing but public domain music/audio files still categorized.)
