Cowfest

A tiny 'moosic festival' set on Spitalfields City Farm off Brick Lane, this one-day event features bovine market stalls selling milk and beef snacks (and beer) as well as music from the Jens Lekman-esque Pasco Tom and Brave Yesterday, a percussive rock band who hail (appropriately enough for a cow-themed festival) from Jersey. Entry is by donation, and all profits go towards buying two cows for the farm. Oh, and there's a fancy dress competition too. No prizes for guessing the theme.
