Banksy Extravaganza

Here's a novelty for the May bank holiday weekend. Banksy has taken over a disused road tunnel in south London for use as exhibition space a half-mile long! The entrance is in Leake Street, Waterloo, London. He invited 29 other graffiti artists to join him in decorating the tunnel, but he kept the location secret until this morning. BBC London News was there like greased lightning. He calls it the Cans Festival! It opens to the public tomorrow for three days. Pick your way between crashed cars and add your own graffiti to the tunnel wall.
