An interesting blog, This Mornin' I Am Born Again posted several examples of different modern artists covering Art Gillham's song Hesitation Blues. Gillham (1895-1961), not only wrote the song, he was a pianist and vaudeville performer. To learn more about him and the song, click his name above.
This particular blog post features Justin performing Hesitation Blues Live and Dave Van Ronk, The Avett Brothers, The Old Crow Medicine Show, Leadbelly, and of course Mr. Gillham himself. Check it out here.
