I met this fellow around 11pm on Millenium bridge. I was on my way from an event at the Hayward gallery to meet the cricketers on the edge of the City. In the middle of the bridge was a party, people testing their new sound system. I convinced them to bring it along. You can never have too many systems. Even when if the police politely ask you to turn it down, as they did to us around 2am, in our only and very brief encounter with the blue that night.
