Clowns, being almost human, are susceptible to the elements just like the rest of us. And there were plenty of elements at Stockley Gardens yesterday. People huddled in parka'd, hooded clusters while artists sat glowering in the dim gray light. Okay, maybe it wasn't all that bad. But there was definitely an air of duty to the trudging festivalgoers making their obligatory appearance at this venerable event. And it was for a very good cause, so nobody really minded. The high point of the afternoon for me was seeing glum clowns. I can't get enough of that.
