I recognize those guys !
Beuaregarde Bouffant and the Boofheads with their roadies and clingons.
Looks like a couple of friends of Ellen de Cheeziness came along too.
They're here for the World Buskers Festival, currently being held "over the hill" in Christchurch.
Not much bio. material about them, except that they're from "somewhere in Texas". Probably from somewhere where the air's pretty thin.
And undoubtedly acquaintances of our very own Wisterialy.
