If you've been fortunate enough to take a SERE course there's an excellent chance you've had Rudyard Kipling's poem Boots branded on your mind. It's a special poem to SERE graduates. But simply reading it's words isn't particularly satisfying, you've likely yearned to hear it in a particular audio form. I don't know if this is the exact audio but with it's emotion and poor audio quality, it's close enough.
This reading makes the Library of Congress' National Jukebox project worth every penny to me! (actual poem starts at ~34 seconds)
