THEY NEVER learned how to do hands properly, did they? Flared of arm and cosmopolitan of make up, the residents of Pigeon Street pottered about their middling adventures, with a song here, a joke there, and nary a care for the rising tide of garbage conservatism threatening their peaceful, multicultural existence.

Pigeons played minor role, as did classic ’80s electric tom-toms.
