The manuscript from The Man Who Went to War by Langston Hughes is available at the Library of Congress:

The Sound Recording (click) has not been digitized, which I believe means you have to go to the Library of Congress to listen. It's a bit of a process for non-academics to get a library card for the Library of Congress. I did it, and it was a thoroughly enjoyable experience - like Alice going into Wonderland (Abby Sale led the way, and then Joe started flirting with a folklorist in a darkened tunnel, and the rest is history...)
