On the Friday at Wacken, there was an announcement made in the morning. All in German, then the important bits repeated in English. Now, me and a friend were sure the announcement mentioned something about a special guest appearing on the Saturday. And we spent some time speculating about who it might be - and in the end we never saw anything unexpected! Was there someone added to the line-up on the last day? If so, who? Or did we just misunderstand the announcement?
