Here is a link to an hour long interview with Robert Crumb that Eli Smith from the Down Home Radio podcast conducted at my apartment last month when Robert was in town..JOhn spins some rare 78rpm's while Eli asks questions..and we also play a few tunes with Robert(on mandolin)!
So listen to it and get your full nerd on!
