From Road Kid to Writer is from StoryWorks.TV. This documentary is based on Jim Tully, the first biography of the vagabond, boxer and hard-boiled writer who rocked Hollywood during the Roaring Twenties. As has been noted, Tully is the most famous writer you've never heard of. He also authored Beggars of Life, the 1928 William Wellman directed film starring Wallace Beery and Louise Brooks.
Here is a related video. It is a musical short by Eric Taylor. It is called "Tully's Titles." Taylor is an American singer-songwriter from Texas. He is known for his anecdotal songs which often take the form of short stories. In addition to Taylor's seven solo releases, his songs have been recorded by Nanci Griffith, Lyle Lovett and others. "Tully's Titles" contains a Louise Brooks sighting! [I will post another video excerpt tomorrow.]
