I have just finished a project recording selected pieces of Twain's writings and posting them onto my facebook page and to YouTube. The last one (#156) is entitled "Autobiographical Dictation of December 2nd, 1907 (Andrew Carnegie, Theodore Roosevelt, Tom Sawyer, & P.T. Barnum OR: The Insanity of the President)"
You can find that one here: https://youtu.be/6jmL_MdeLsw
Next up will be "Tom Sawyer" in full, followed by "Huck Finn" in full; one chapter per day (and twice on Sundays, perhaps).
