Brian and Roger are currently in Cologne. There was a press-conference today for the launch of "We will rock you" which premieres here on Dec. 12th.
As you can see in the "koelner-stadt-anzeiger"-newspaper report, they received a golden disc for the MK-DVD-Sales in germany during that press-conference.
So that must be almost solely the pre-orders, as it was released on Monday... quite impressive !!! link
(Scroll down to the headline "Musical: Queen-Mitglieder versprechen „Rock'n'Roll”")
PS: Rog is called "John Taylor" in the article... Journalists ! Must have been a DuranDuran-Fan... ;-)
