Coming to the opening of Jay Jopling’s White Cube Squared yesterday evening one was stunned by the crowds. I have never seen so many people at an art opening. But then one noticed that there actually were two crowds: one in front of the gallery, trying to get in, and another standing across the street by the fence of the park in the middle of Hoxton Square, gawking at the first crowd and holding onto bottles of the ubiquitous Becks beer. It soon became obvious that the second crowd was standing around the spot where free beer was on offer. A useful tip for supergallerists.
