Crossing Westminster Bridge, dodging tourists. A Scot in multi-tartan, cap, sporran and all the trimmings is playing on his bagpipes. Foreigners pause to have their photos taken next to him. As I pass a young woman (no idea where from) stoops to put some coins in an upturned battered hat on the pavement in front of him, then places herself by his side to be snapped by her friend. 'And where're you from?' asks the bagpiper in a strong east London accent. Joy!
