Couldn't remember if this was one of the holiday tapings.
They kind of have to announce it don't they? More people tune in if they know Sting is on, wouldnt they?
From a hardcore fan that is definitely tuning in every week, the spoiler sucks. But their ratings aren't good enough to rely on that group.
I still don't think knowing Sting will be on increases the ratings, but theres a chance and they have to do it that way.
