After recent criticisms from luvvies, Tony Blair may be thinking of distancing himself from celeb endorsements, but Ken Livingstone has no such problems. Famous people appear to be queuing up to back his campaign to be allowed to stand for the post of Mayor of London. He certainly has the comedy glitteratti turning out in force for a benefit - entitled "Stand Up For Ken" - this week. A most impressive bill, comprising Jo Brand, Phill Jupitus (right), Arthur Smith, Kevin Day and Gina Yashere, is complemented by a special treat, a performance by the original agit-prop troubadour himself, Billy Bragg.
