I thought Darkstar Hop Head was on sale as well?
When this broke 2 or 3 weeks back, Attila said the concourse signs didn't have Darkstar on because they didn't have the logo. But, to my eyes anyway, it was clear that the signs were finished - there was no space to add anything else on, including the other drinks that are supposed to be available such as a proper cider (Symonds, I think, was quoted) and Guinness, possibly others.
