From the English Tradition, how about "The Farmer's Boy"?, "Scarborough Fair" (tell him to plough me ... etc). I'll try to come up with others.

I attend several singarounds out in rural parts of eastern England, and there a several "old boys" who turn up and sing obscure songs with a farming theme, some from the Music Hall ("Jollity Farm") and others from the point of view of the farm labourer ("Did you ever see a farmer on a bike")

I'll trace the thread and set some pointers when I get time.
