If you can't get up to Spitalfields tonight for the turning on of the Old Market lights with Gilbert & George, then don't forget that today is the day that the Norwegian Christmas tree is all lit up in Trafalgar Square.
According to Ken's website the traditional ceremony will take place at 6pm and will be attended by the Mayor of Oslo, Per Ditlev-Simonsen.
Before that though there is a 'pre-ceremony concert' with "bell ringing in the square to attract the public to the performance area", the Oslo Cathedral Boys Choir and "Platinum-selling Scandinavian artist Sissel".
Some quick tree facts:
One fact we can't find: where do the lights themselves come from? Are they just kept in an old cardboard box in the loft at City Hall? Does Ken have to sit there and untangle them all in the days leading up the ceremony?
