I'll second that one. Maybe several of the Union numbers drummed up by all those warm fuzzy pinko commie bastards (:>) in the thirties, like The Union Maid, Get Thee Behind Me Satan, Which Side Are You On, and at least one variant of the Talking Blues Ad Infinitum. By Alice's delightfully challenging definition it would probably be the "Asteroid Walking Talking Blues" by Cosmos Bastion and the Parsecs...:>).
