When Bob Dylan dances onstage - and he does seem to dance, after a fashion - at 9.15, it is easier than usual to draw battlelines in the crowd. Mostly, they have been at this Feis festival in Finsbury Park (very much a pack-em-in and get-em-pissed throwback to the pre-boutique era) all day, have had a selection of rain, mud, corporate beverages and Cranberries thrown at them, and in some cases are probably expecting The Saw Doctors to headline the main stage.
