Above, frogman43 mentions a 1969 Tanzanian safari by a group from Petersen Publishing that included Elmer. Some audio recordings were made of campfire conversations. These recordings may still be available on CD: http://www.sixgun-forums.com/ElmerKeith/content/elmer-keith-tanzania-safari-1969-cd-set

Posted on that website there are a couple of teaser snippets of Elmer talking. The audio mp3 tracks may open from these links.
