I recall reading on the liner notes for the Mark Twain Tonight LP that Hal Holbrook used both rare film footage to study his manner and gramophone recordings to study his voice. They exist somewhere. Achtung: Here Richard H. Cracroft raises his (wizened) head: I use the film," Mark Twain Gives an Interview" (1961, Color, 16MM; 14 min.) whenever I teach Twain. Important to an otherwise excellent Hal Holbrook "interview" with high school students in the Connecticut home and pool room, is the thirty-second original clip of Twain at the home. It is the only place I have found it available and treasure it. I suppose that your campus audio-visual centers can get this; it's probably on video now. Richard H. Cracroft Brigham Young University
