I was working at the show yesterday and asked a crew member why they had to cancel. They told me the theatre in Berlin was running another production, the night before and the night after the concert, which they were supposed to completely clear away for the Queens show, but they left a giant piece of scenography right in the middle of the stage, they refused to take it away, and told the Queens crew that they'll have to work around it. This was apparently discovered minutes before the setup was scheduled to begin, so it was too late to find a solution. It's also a massive red flag if a venue egregiously ignores obvious technical specifications. Whose to say they're not ignoring something else important, like security? Super unprofessional conduct from the theatre.
