Some people don't use the underpass on the way to work. They don't save any time by doing this. It's large and arena-like, with indirect paths, but on the roads above they have to wait for a gap in 40mph traffic, and get through it without the help of stop signs or pedestrian pomp. There's a story going round I haven't heard.
A man rapped his head off right in front of us. It tumbled to the front of the stage and was picked up and passed, rhyming the whole time, between three hundred pairs of hands raised high in disbelief. His body stayed onstage in a floor-length black gown, shimmying and jerking with a microphone held to its neck.
