Right for a laugh my mate and I were thinking of going to see them in London at the O2 in December for a girlie day out. I asked her what is the most she would pay and both agreed no more than £40.00. To get a priority booking you had to register details on their website which i did back in July. Have just received details and the cost of the decent seats are £75 and upper tier seats £55!!!! now for anyone who hasn't been to the O2 the upper tiers are like being on the top of mount everest. Totally lacks atmosphere and the sound quality is bad. Will save me money and wait for the performance on sky.
