Wurzel trees aren't real, the band is called The Wurzels; and it's a bastardisation of Mangelwurzel - which is one of the 89,471,342 types of turnip we have here in England. We don't do many things very well, just colonialism and root veg.

And yes, I think there's something to the loneliness in cities idea.... I have lived in London for a decade, but I still go 'home' to the muck-spreading smell and the root veg stew. :o)
