The Llewyn Davis character in the brilliant Coen Bros. film suggests, I don't say represents, Dave van Ronk. So let's start with some tunes (not necessarily the renditions) from the movie done by the Mayor of MacDougal Street.
Dink's Song. Marcus Mumford and Oscar Isaac version. Punch Bros. live version. Carolyn Hester. Odetta. Dylan.
Tom Paxton, The Last Thing on My Mind
Justin Timberlake, et al. Five Hundred Miles. PPM version. Journeymen version.
